Answer:
sarcoplasmic reticulum deteriorates and ATP production is stopped
Explanation:
Rigor mortis is the third stage of death characterized by stiffening of joints and muscles in body. The stiffening occurs because muscles are not able to return to the relaxed state. There are two reasons for rigor mortis, depletion of ATP and increase in calcium concentration in cytosol. Due to these factors the actin-myosin crossbridge is not able to break and the muscles remain in contracted state.
Sarcoplasmic reticulum deteriorates and calcium is released into the cytosol. Sarcolemma ( covering of muscle fiber ) also breaks down releasing extra calcium into the cytosol. Calcium is responsible for formation of actin-myosin cross bridge and when its concentration increases the bridge is formed continuously leading to stiffening of muscles and joints.

Hey friend!
Let's figure this out
Fragmental sedimentary rocks include shale, sandstone, conglomerate, <span>salt, </span><span>breccia, </span><span>limestone, </span><span>chert, </span><span>dolomite, coal, </span><span><span>siltstone, and gypsum.
As you can see, Gneiss is not listed among examples of fragmental sedimentary rock. So your answer is B.
