Answer Choice 3 is right.
Original Statement
"If it is warm, then I go swimming"
Step 1.) Switch it
I go swimming, then it is warm
( The sentence in step 1.) is called the converse, which is not always equivalent to the original statement)
Step 2.) Now negate both the hypothesis and conclusion of Step 1.)
I don't go swimming, then it is not warm - > Contrapositive [this is what you want]
Solution: Answer 3.)
