Final answer:

The indicator of a MH crisis among the options is D. Cola-colored urine, which shows myoglobinuria. It is a symptom associated with the rapid breakdown of muscle tissue in Malignant Hyperthermia.

Step-by-step explanation:

The subject of this question is Medicine, and it concerns identifying indicators of a Malignant Hyperthermia (MH) crisis, which is a severe reaction to certain drugs used for anesthesia. Considering the options given, D. Cola-colored urine is an indicator of an MH crisis. This symptom reflects myoglobinuria, which can occur as a result of rhabdomyolysis, a serious condition often associated with MH where muscle tissue breaks down rapidly.

MH crises typically have signs like muscle rigidity, rapid heart rate, high body temperature, and dark urine due to myoglobinuria. Symptoms usually appear shortly after exposure to triggering agents, not days later.
