The given reaction is:

11eaa64f_8f87_2f95_a696_93b7a2821692_TB5258_11: 4He + 14N → 17O + 1H

The Q value of the reaction can be calculated as:

Q = (mass of reactants - mass of products) x c^2

We are given the following atomic masses:

Mass of alpha particle (4He) = 4.002602 u
Mass of nitrogen (14N) = 14.003074 u
Mass of oxygen (17O) = 15.994915 u
Mass of hydrogen (1H) = 2.014102 u

Substituting these values in the Q equation, we get:

Q = (4.002602 u + 14.003074 u - 15.994915 u - 2.014102 u) x (931.5 MeV/c^2/u)

Q = -3.11 MeV

Therefore, the correct answer is choice C (-3.11 MeV).
