Answer:
Option A. Double Replacement
Explanation:
A double displacement reaction is a kind of reaction in which there is an exchange of the ions of the two reactants to form a different products. In the equation, K in KOH displaces H in H3PO4 to form K3PO4 and also, the H combines with OH to form water.
H3PO4+3KOH -> K3PO4+3H20
Calcium, because when it becomes an ion, it loses two electrons and gets rid of its M shell, decreasing its ionic radius. The rest are anions, which increase in ionic radius because the effective nuclear charge decreases.
