Option 1 states that the energy of the photon is 10 MeV. This is the correct answer. The energy of a photon is directly proportional to its momentum. In this case, the momentum of the photon is given as 10 MeV/ c. Since the speed of light, c, is a constant, the momentum value can be directly converted to the energy value. Therefore, the energy of the photon is also 10 MeV.

Option 2 states that the energy of the photon is 100 MeV. This is not correct. The energy of the photon is 10 MeV, not 100 MeV.

Option 3 states that the energy of the photon is 1 MeV. This is not correct. The energy of the photon is 10 MeV, not 1 MeV.

Option 4 states that the energy of the photon is 0-1 MeV. This is not correct. The energy of the photon is a positive value of 10 MeV, not a negative value or a range of values from 0 to 1 MeV.

Therefore, the correct answer is option 1, which states that the energy of the photon is 10 MeV.
