C. cardiac muscles become extremely excitable
D.cardiac muscles contract weakly.
E cardiac muscles become lethargic.​

Answer 1

Under conditions of hypercalcemia, cardiac muscles become extremely excitable.

Step-by-step explanation:

Under conditions of hypercalcemia, cardiac muscles become extremely excitable. Hypercalcemia is a condition characterized by abnormally high levels of calcium in the blood, which leads to the underactivity of the nervous system. This results in an increase in excitability of cardiac muscles, making them more prone to spontaneous contractions and irregular heart rhythms.
