In a synthesis reaction between calcium (Ca) and phosphorus (P), we typically form a compound that combines the two elements in a way that adheres to their valences.

Calcium has a +2 oxidation state, and phosphorus typically has a -3 oxidation state in compounds. To balance the charges, we can use the following approach:

- We need 3 calcium ions to balance the -6 charge from 2 phosphate ions. So the formula for the product will be \( Ca_3P_2 \).

Thus, the correct answer is **Ca3P2**.
