The correct answer is B. Set BOOTPROTO to NONE and ONBOOT to yes. BOOTPRO is set to NONE for static assignment (check this link https://www.dummies.com/programming/networking/network-administration-linux-ifcfg-files/ ) And ONBOOT specifies YES to o indicate whether the device should be enabled when Linux boots up.
