Q-value of Nuclear Reactions

Assertion (A): The Q value of nuclear process is Q = total final binding energy - total initial binding energy.
Reason (R): The Q value of nuclear reaction initially appears in form of kinetic energy of products.
 
Both (A) & (R) are true and the (R) is the correct explanation of the (A)
Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(A) is true but (R) is false
Both (A) and (R) are false

Solution:

Assertion (A) is true by definition of Q-value: \(Q = sum BE_{products} - sum BE_{reactants}\). Reason (R) is also true, as the Q-value manifests as kinetic energy of products in exothermic reactions. However, (R) describes the consequence of Q-value, not its definition, so it's not the correct explanation for (A).
