Relax buddy.... I'm yet to recieve knighthood..... :)

statement 1 : v-k is +ve ..... you can have many sets for (v,k) .. like (1,0) , (2,0) ..... in all these cases value of v^3-k^3 will be different .... Not suff

Statement 2 : v-k = 6 ... again you can have (7,1) .... (106,100) ...... So Not suff....

Combine 1 and 2 still not suff... So the answer is E....
