C
as colonoscopy is done after the age of 50yrs for the general population

The correct answer is C:
The US Preventive Services Task Force recommends colonoscopy beginning at age 50 years for men and women. Three consecutive FOBT specimens is a proven screening method but it suffers from diet interference, causing false-positive results. Flexible sigmoidoscopy, DRE, and a single FOBT are not adequate screening strategies.
