trigger Jenkins jobs when a folder inside Git repo changes

[Mark Simon]

My Git repo contains 3 folders ( All 3 folders are in 1 repo)

A

B

C

I have 1 jenkins job ( Parameterised and remote trigger enabled via URL call) which need to invoke based on the folder changes

jenkins/........./.../build1

jenkins/........./.../build2

jenkins/........./.../build3

jenkins/........./.../build4

Ex. If folder A changes on the Git i need to invoke build1 & build2

If folder B changes on the Git i need to invoke build3 & build4

Can you suggest a solution to this?
