First person to answer gets 30 and posible brainaly

A) Quantitative and D) Discrete.

Explanation:

Quantitative --> you are measuring how long the mice take to go thru the maze, so that is for time

Discrete --> the mice have to reach the end point sooner or later, so the next word is discrete.

I hope this helps!

Edit: The correct answer was (as told by the questioner) A) and B). I don't know exactly why it was B), but that was the correct answer. To me, A) and D) made more sense. Thanks.
