I think you are confused with the options. D,E,F,G are not possible.
Consider option E. It says "
Both C1 and C3 are required". But actually either of them will suffice(though there is no harm if you apply both options while
testing in code. It will work fine.)

But i have checked the options also and still find that except option b all the options compile the code.
Here's the exact code.
