Comments

So, it should be CSL ?? nd sir, i m not good in pumping lemmas..but ya, I think it requires division so shud be CSL.

yes. Whatever you can write a C code for, will be a CSL. Options D and E are also true. But CSL is the most appropriate.

@arjun sir :can't we write the above language as -:

$L=\left \{ a^{n}b^{m} | n=k \times m\right \}$ there is no way to check this language using  stack.
