Which of the following compounds will form significant amount of meta product during mono-nitration reaction?

Aniline in presence of nitrating mixture  $\left(conc.HN{O}_3+conc.H_{2}S{O}_4\right)$
gives significance amount  $\left(\simeq 47\%\right)$ of meta-product because in presence of $H_{2}S{O}_2$ its protonation takes place and anilinium ion is formed.

Here, anilinium ion is strongly deactivating group and meta-directing in nature. So, it gives meta-nitration product.
