I believe it would be declarative because it is stating a fact.
Interrogative is a question and will allmost always end in a question marks.
Imperative is an order and will almost always end in a period.
Exclamatory shows excitement or concern ends most often with a exclamation mark.

The answer to this would be verbal irony.
Irony is a discrepancy or an incongruence between what is anticipated and to what it actually is. There are three types of irony. One would be verbal irony which, as the name suggests, revolves around speaking or what is said. The other two would be dramatic irony and situation irony. Dramatic irony is usually used in plays, dramas, and the like that involves the audience's awareness. Situation irony would be more involved with what's happening around.
