Arrangethefollowing stretching exercises in a sequential order from toe to head.

(A) Pectoral stretch
(B) Quadriceps stretch
(C) Thoracic extension stretch
(D) Lumbar extension stretch

The correct option is (B), (D), (A), (C).

To arrange the given stretching exercises in a sequential order from toe to head (inferior to superior direction in the human body), we need to identify the anatomical location of the primary muscle groups targeted by each stretch:
1. (B) Quadriceps stretch: Targets the quadriceps femoris muscles, which are located in the anterior compartment of the thigh (lower body). This is the lowest (most inferior) muscle group among the options, closest to the toes.
2. (D) Lumbar extension stretch: Targets the lumbar spine region (lower back), which is situated just above the pelvis and thigh region.
3. (A) Pectoral stretch: Targets the pectoralis major and minor muscles, which are located in the chest area (anterior thoracic region). This region lies superior to the lumbar spine but inferior to the upper thoracic spine/neck area.
4. (C) Thoracic extension stretch: Focuses on extending the thoracic spine (upper/mid back) and shoulders, moving up towards the head region (most superior).

Therefore, sequencing these stretches from toe to head gives the order: (B) ⇒ (D) ⇒ (A) ⇒ (C).
