Compound having low K sp precipitated first

Q. Solubility product of $B a (O H)_{2}$ and $A l (O H)_{3}$ are $1.8 \times 1 0^{- 10}$ and $2.4 \times 1 0^{- 20}$ respectively. If both $A l^{+ 3}$ and $B a^{+ 2}$ ions are present in a solution, which one will be ppt on addition of Ammonium hydroxide solution

$B a (O H)_{2}$

$A l (O H)_{3}$

Both are precipitated at same time

Both are not precipitated

Compound having low $K_{s p}$ precipitated first
