Correct Answer:

no contraction

Explanation:

EDTA(Ethylene diaminetetraacetic acid), is a compound that acts as a chelating agent, reversibly binding with iron, magnesium and other metal ions. It is used in certain culture media bound with iron, which it slowly releases into the medium and also in some forms of quantitative analysis. When EDTA is injected into the muscles, it paralyses the muscles by combining with calcium ions.
