Write the following set in the set-builder form $E=\{1,4,9.......,100\}$

$\begin{array}{1 1}(A)\;E=\{x : x=n,n\in N\; and \;n < 9\}\\(B)\;E=\{x : x=n^4,n\in \;N\; and\; n < 10\}\\(C)\;E=\{x : x=n^2,n\in N \;and\; n < 11\}\\(D)\;\text{None of these}\end{array}$

$E=\{x : x=n^2,n\in N \;and\; n < 11\}$
Hence (C) is the correct answer.
