If $L$ and $M$ are respectively the coefficient of $x^{-7}$ in $\left(a x+\frac{b}{x^2}\right)^{11}$ and the coefficient of $x^7$ in $\left(b x^2+\frac{a}{x^2}\right)^{11}$, then $L+M=$

$\frac{1}{b}\left[\right.$ coefficient of $x^{-6}$ in $\left.\left(a x+\frac{b}{x^2}\right)^{12}\right]$

$\frac{1}{a}\left[\right.$ coefficient of $x^{-6}$ in $\left.\left(a x^2+\frac{b}{x}\right)^{12}\right]$

$a\left[\right.$ coefficient of $x^{-10}$ in $\left.\left(a x+\frac{b}{x^2}\right)^{11}\right]$
