Among the following the correct statement is

                $=a^9$

B) $a^2.{\left(a^3\right)}^4 =a^2.a^{12}$

$=a^{14}$   it is the correct statement.

$\therefore$  given statement $a^2.{\left(a^3\right)}^4 =a^9$  is wrong

C) ${\left(x+y\right)}^{5 }=x^5+5x^{4}y+10x^3{y}^2+10x^2{y}^3+5x{y}^4+y^5$

it is the correct statement

$\therefore$  given statement ${\left(x+y\right)}^{5 }=x^5+y^5$  is wrong

D) $a^5.a^6.a^{0 }=a^{5+6+0}$

$=a^{11}$   it is the correct statement

$\therefore$  given statement $a^5.a^6.a^{0 }=a^{10}$  is wrong
