${ } _ { 2 } ^ { 4 } \mathrm { He } : \quad 4.002603 \mathrm { u }$
1p: $\quad 1.007825 \mathrm { u }$
What is the $Q$ -value (or reaction energy) of this reaction? $\left( 1 \mathrm { u } = 931.5 \mathrm { MeV } / \mathrm { c } ^ { 2 } \right)$

• A) \(13.57 \mathrm { MeV }\)
• B) \(17.53 \mathrm { MeV }\)
• C) \(15.37 \mathrm { MeV }\)
• D) \(17.35 \mathrm { MeV }\)
