Answer:
The muscles that the personal trainer would expect to be shortened are Sternocleidomastoid and pectoralis major. The right answer is Option A.
Explanation:
While assessing one's posture, if a person has protracted shoulders and a forward head, then the trainer focuses on working on the sternocleidomastoid and pectoralis major muscles. The former is one of the largest superficial cervical muscles which helps in the rotation of the head to the opposite side and flexion of the neck. The latter is responsible for shoulder joint movement. At first, it causes flexion of the humerus like lifting a child. Secondly, it adducts the humerus like when one flaps his/her arms. Working on these muscles helps to correct the posture of the concerned person.

Bradycardia is the most ominous sign of impending cardiopulmonary arrest in infants and children.
Bradycardia is a slow heart rate. The hearts of adults at rest usually beat between 60 and 100 times a minute. The heart beats fewer than 60 times a minute.
Bradycardia can be a serious problem if the heart rate is very slow and the heart can't pump enough oxygen-rich blood to the body. If this happens, one may feel dizzy, very tired or weak, and short of breath. Sometimes bradycardia doesn't cause symptoms or complications.
Cardiopulmonary arrest is the cessation of adequate heart function and respiration and results in death without reversal.
