(A) Based on the evolutionary tree of plants provided in the $NCERT$ textbook (Chapter: Evolution,Section: $A$ Brief Account of Evolution):$1$.

The label $Q$ corresponds to 'Psilophyton',which are considered early vascular plants.$3$. The label $R$ corresponds to 'Tracheophyte ancestors' (vascular plant ancestors),which evolved from the Rhynia-type plants.Therefore,the correct sequence is $P$ - Seed ferns,$Q$ - Psilophyton,$R$ - Tracheophyte ancestors.
