Question
If 
- none of these
Hint:
We are given a function. We have to find the double derivative of the function. Before finding the second derivative, we will simplify the equation.
The correct answer is: 
The given function is as follows:
y = sin2xsin3xsin4x



We will resubstitute the values.

None of the option matches.
So, right option is "none of these".
