Answer:
The answer is A. It's too bad it's raining; I wanted to go for a swim.
Explanation:
In the multiple choices offered as possible answers, the words that are written differently are it's too bad it's raining; I wanted to go for a swim. Option A is the correct answer because it's is a contraction of it is, both times it appears in the sentence; the first too must be writen with two o's because it expresses an amount and the second to is only written with one o because it is a preposition before a verb.
