I need to have some choices
Answer: 3
Explanation:
Given :
numC = 12
while numC > 3:
numC = numC / 2
Initial value of numC = 12
The condition checks if the value of numC is greater than 12, only then will the statement be executed and the loop isn't altered
numC = 12 is greater Than 3 ;
numC = numC/2 = 12/2 = 6
numC is now 6 ;
numC = 6 is greater than 3
numC = numC / 2 = 6/2
numC is now 3
numC = 3 is not greater than 3 ; hence, loop terminates (condition isn't met)
Hence , numC = 3
