Answer
B. Mass of 1.007 atomic mass units
Explanation
An electron has a negative charge, a very small mass (much less than 1 atomic mass unit), orbits the nucleus in the electron cloud, and can be gained or lost to form ions. The mass of 1.007 atomic mass units is characteristic of a proton, not an electron.
