Short Answer

A proton has enough mass energy to decay into a shower made
up of electrons, neutrinos, and their antiparticles. Which of the following
conservation laws would necessarily be violated if it did: electron lepton number or baryon number?

The Baryon number will be violated.

Step 1: Concept used to solve the question.

Conservation of lepton number:

In all particle interactions, the net lepton number is conserved.

Conservation of baryon number:

In all particle interactions, the net baryon number is conserved.

Step 2: Finding which conservation law would be violated

As we know, the electron lepton number of protons is zero. If there is an equal number of electrons and their anti-particles, the lepton number could be zero.

And the Baryon number of the proton is one and of other particles zero. Therefore Baryon number will be violated.
