The binding energy per nucleon of ${ }^{10} \mathrm{X}$ is 8 MeV and that of ${ }^{11} \mathrm{X}$ is 7.5 MeV where X represents an element. The minimum energy required to remove a neutron from ${ }^{11} \mathrm{X}$ is

• A

  7.5 MeV
• Correct answer
  B

  2.5 MeV
• C

  8 MeV
• D

  0.5 MeV

Hence, the correct answer is option: 'B'.
