definition 1
definition 2
definition 3
definition 4

Explanation:

The sentence mentions "latch the bolt on the window". Latching is related to locking. Definition 3 says "a bar that slides to lock something", which fits the context of locking a window. Definition 1 (a screw for fastening) is for a different kind of fastening (like in machinery), Definition 2 (a strike of lightning) is about weather, and Definition 4 (a roll of fabric or wallpaper) is about materials.

Definition 3
