Question that’s keeping me up at night

If you have 7 locks and 50 keys, each lock can be opened by one key only, what would be the fastest way to open one lock? A) Try the keys one at a time on a single lock. B) Try one key at a time on all locks one by one.

Personally I think B sounds like the right choice, but it is time consuming.

What do y’all statisticians think??
