Vanishi Jain from Delhi Public School , Noida
Class : Class 5
It should be d . Please tell us master admin

Ans 2:

Abhinav Huralikoppi from Sanskaar English Medium School , Hubballi
Class : Class 5
The answer should be A or B since if the answer A, that is 0, it can be the answer as any number multiplied by 0 is equal to 0. But, if the answer is B, that is 1, it can be the answer if the question has been framed wrongly, that is, if the question would have been "What is the common factor of all the numbers" since all numbers are divisible by 1. But how could the question possibly go so horribly wrong?
