Use the process of elimination.

An α decay would change the atomic number from 7. So it cannot be option 1. A beta decay requires 2 particles to be emitted e^– / e⁺ and r / r^– option 2 and 3 don’t satisfy this. This leaves us with the 4th option.

The correct answer is: Electron capture by the nucleus with emission of a neutrino.
