CorrectNot quiteAnswer A

Correct answer: A

Every shirt is a jacket and no jacket is a coat, so no shirt is a coat.
The sweaters that are coats are therefore not shirts. Some sweaters are not shirts: I follows.
Sweaters that are not coats are unrestricted and may be shirts, so 'No shirt is a sweater' is not definite. II does not follow.
Only I follows.

Worth noting

First combine the first two statements (No shirt is a coat), then join that with the third. Joining 'No + Some' gives a Some-not starting from the Some group.

Concept: Reducing three statements to two, then No + Some
