P and Q are boron and silicon, as they yield boranes and silicanes respectively.

Q. Two elements $P$ and $Q$ react separately with highly electropositive metal to form binary compounds, which upon hydrolysis yield mixture of boranes and silanes? $P$ and $Q$ respectively are

$B$ and $A l$

$S i$ and $B$

$B$ and $S i$

$A l$ and $B$

$P$ and $Q$ are boron and silicon, as they yield boranes and silicanes respectively.
