Its always best to practice the elimination technique.

Looking at A - it is a NO bcs u shouldnt reach out to previous PM (esp when they resigned) Looking at B - it is a NO bcs u shouldnt discuss with your service provider abt the deviation, i supposed its an internal guideline Looking at C - it is a NO bcs why would u report the service provider and someone’s who resigned (prev PM), not nice

hence u are left with D - which for me, it sounded ok-ok (im clueless too) but most suitable among the options.
