Station using 20/40MHz, does it inherit AP channel-width?

Hello folks,
Thanks for taking the time. I’m curious about channel width in the following scenario:

CPE/Client:
mode=station
band=20/40mhz-Ce

AP:
mode=ap-bridge
band=20mhz

My question, will the Client operate within 20MHz because of the AP settings? Or will it operate in 40Mhz regardless of AP settings?

Thanks in advance one more time.

Cheers!

The client will operate at 20 MHz
