i think its B recursive but not CFL

Yes i think its option B recursive but not CFL

Yes It will be Recursive and can't be CFL  bcz if the length is in square i.e power is non-linear and whenever the length is non linear like factorial, underoot etc then it can't be CFL

L = (a+b+c)* , isn't it regular ?
