Jack found the broken umbrellas ______. A. in a shop B. in a closet C. on a bus

Let's think through the options.
If someone finds broken umbrellas, they’re usually stored somewhere out of the way or discarded, not typically displayed for sale in a shop.
On a bus, you might forget an umbrella, but "the broken umbrellas" suggests specific ones known beforehand — less likely to be on a bus randomly.

The most natural place to find a collection of broken umbrellas that belong to someone is in a closet (where old/unused items are stored).

So the best answer is:
B. in a closet ✅
