Correct option is C
Solution- The Correct Answer: C. but
But → used to show contrast between two opposite ideas.

And → adds similar ideas (not contrast).
So → shows result (not suitable here).
Because → shows reason (doesn’t fit the meaning of contrast).
Correct: I wanted to play outside, but it was raining.
