Can You Figure Out Which Triangle Comes Next?

Hi everyone, we’re back with another puzzle.
First, thank you to everyone who took part in our previous puzzle. We received several interesting answers, including some alternative interpretations that made the discussion even better.
As usual, we picked three community explanations that stood out:
u/Small-Tailor6967 — We chose this explanation because it clearly connected both key parts of the pattern: the last shape carrying over into the next box and the shape with the most vertices being shaded. It also explained clearly why those rules lead to B.
u/ChaosRealigning — A very clean and concise explanation. They identified both the continuity rule and the shading rule without overcomplicating the solution.
u/vexedthespian — Another strong explanation that independently recognized the relationship between consecutive groups and that the shape with the most sides is the one that gets shaded.
Thank you to them, and to everyone else who shared a solution. We really enjoy seeing the different ways people approach these puzzles.
Now it’s time for our new puzzle.
Take a close look at the sequence in the image and choose the option you think should replace the question mark.
But don’t just give us the letter. Tell us why you chose it and explain the pattern you found. We’re especially interested in the reasoning that leads you to your answer.
As with our previous puzzles, we’ll select some of the best community explanations and feature them on our website with the Reddit usernames of the people who wrote them.
You can also view the puzzle and submit your solution directly on our website:
https://whats-your-iq.com/en/questions/pattern-recognition/which-triangle-comes-next-in-the-sequence
So, what’s your answer: A, B, C, or D?
And more importantly: what pattern do you see?

Fill the A B C in every column and row

Fill the grid with letters A, B, and C so each appears once per row and column. Outer clues indicate which letter is seen first from that direction.

Is Time Travel and Teleportation the same thing essentially?

This debate has scrambled the brains of my boyfriend and I. The argument is If Time travel and teleportation are essentially the same things? Teleportation = WHERE changes. Time travel = WHEN changes. That being said
Both can happen at once = WHERE + WHEN changes

My argument:
Example: It is Texas 2026 and I want to live 1950 New York. I would TIME TRAVEL there. This is just time traveling bc I want to live 1950 New York, I didn’t teleport there just TIME TRAVELED. Of course I changed setting when I traveled back in time.

Boyfriends argument: Time traveling and Teleportation are the same thing in a sense

Example: For example, if I'm in my room right now and I wanna time travel one hour into the past where I was in the kitchen, theoretically that changes my location, so it's like teleporting.

The definition of time traveling and teleportation essentially changes the meaning of them both. I would like to see what y’all think about this argument, it has been very fun!
