Which of the following statements correctly describes the relative numbers of protons and electrons within the spheres?

A

Spheres LLL and MMM both have more electrons than protons; sphere NNN has more protons than electrons.

B

Spheres LLL, MMM, and NNN all have equal numbers of protons and electrons.

C

Sphere LLL has more protons than electrons; spheres MMM and NNN both have more electrons than protons.

D

Sphere LLL has more electrons than protons; spheres MMM and NNN both have more electrons than protons.
