Incorrect Answer1, 2 and 3
Correct AnswerExplanation:
Calcium is essential for activating enzymes which cause muscle contraction.
Iron helps support continued muscle function by supporting energy production in your muscle cells, so that muscle fibers always have the energy they need to contract properly. Iron also helps muscles store oxygen to fuel muscle contractions, and promotes healthy circulation so that muscles can get additional oxygen from bloodstream.
One need sodium for muscle contraction because it balances potassium to maintain membrane potential.
