Answer 1

The correct answer is definitely choice D. If a month does not have 30 days, then the month is not June.

The definition of contrapositive is "switching the hypothesis and conclusion of a conditional statement and negating both of the sentences."

Example: "If it is raining then the grass is wet"

Contrapositive: "If the grass is not wet then it is not raining."
