Correct answer: C

Both statements only keep towers away from the other two groups. They say nothing about bridges and gates.
Bridges and gates may overlap, or may not: neither I nor II is definite.
The pair 'No bridge is a gate / Some bridges are gates' is complementary, so exactly one of them is true.
Either I or II follows.

Worth noting

Two 'No' statements never give a definite conclusion. It is tempting to 'chain' them into a third No, but that is not valid.
