Solution

The correct option is B
${BiPO}_{4}$

Chemical formula is formed by crossing over the valencies of the elements present in the compound.
Explanation of correct Answer:
${BiPO}_{4}$ -Both ions are trivalent in this compound and hence form the correct formula.
Explanation of Incorrect options:
As the valencies are not fulfilled in the formation of compounds like $CaCl, {NaSO}_{4,} NaS$ . Hence these are not correct.
Hence the correct answer is (b)- ${BiPO}_{4}$
