Question

 

a , c , d all three are right answer please explain if i am wrong.

Answer 1

Option d, is not correct because small-omega is for strictly smaller not equal.

And option C,  is typed mistaken probably.  It would be g(n)=o(g(n)) . Then only it is not correct as,  small-oh is for strictly greater.
