Best answer
Correct option is (a) Ryanodine receptors

The best explanation: When limited amount of calcium ions enter the cell through open channels in the endoplasmic reticulum (ER) membrane, there is a subsequent opening of the ryanodine receptors, causing the influx of Ca^2+ ions in the cytosol – calcium-induced calcium release.
