Options

A. `{:(P,Q,R,S),(4,2,3,1):}`
B. `{:(P,Q,R,S),(4,2,3,3):}`
C. `{:(P,Q,R,S),(2,1,3,4):}`
D. `{:(P,Q,R,S),(3,1,4,2):}`

Explanation

(P). Total energy, total linear momentum, total angular momentum is conserved but mass is converted into energy.
(Q). Total energy, total linear momentum, total angular momentum and toal mass is conserved.
(R). Total energy, total linear momentum, total angular mometum and total mass is conserved.
(S). Total energy, total linear momentum, total angular momentum is conserved but mass is converted into energy.
