b. complementary proteins
Explanation:
Complementary proteins are proteins that contain all adequate amounts of the essential amino acids when two or more protein sources that are deficient or low in some amino acids are combined together to compensate for the deficiency of the other. The protein sources can be eaten together in a meal or consumed the same day to get a complete protein.

They have the same number of protons as electrons.
Explanation:
Protons are found in the nucleus of the atom and have a positive charge while electrons orbit around the nucleus and have a negative charge.

When an atom loses an electron its charge turns positive while when it gains an electron its charge turns negative.
