Answer: The correct answer is Option A.

Step-by-step explanation:

We are given some ions, which are:
$Na^+,PO_4^(3-),V^(3+)\text{ and }Cl^-$

The compounds which may be formed from these ions will be
$Na_3PO_4,NaCl,VPO_4\text{ and }VCl_3$

Precipitates are defined as the substances which are not soluble in water at any temperatures. They remain undissolved in water.

Out of the formed salts, the soluble ones are
$Na_3PO_4,NaCl\text{ and }VCl_3$

remains insoluble in water and thus, the correct answer is Option A.
