The number of spiracles in cockroach is 10-pairs (2-pairs in thoracic and 8-pairs in abdominal region).  The thoracic pairs of spiracles are present on pleuron between prothorax - mesothorax and metathorax. Each spiracle opens into a chamber called atrium.  After atrium the tracheal tube ramifies into fine branches of tracheae, and then tracheoles.

Path of air/O2 during respiration in an adult male Periplaneta americana:

Spiracle in metathorax:
- The air/O2 enters the body of Periplaneta americana through spiracles, which are openings on the sides of the body.

Trachea:
- The air/O2 passes through the trachea, which is a system of tubes that carries air throughout the body.

Tracheoles:
- The tracheoles are smaller tubes that branch off from the trachea and penetrate the tissues of the body.

Oxygen diffuses into cells:
- Once the air/O2 reaches the tracheoles, oxygen diffuses into the cells of the body.

Therefore, option B is the correct answer as it accurately describes the path of air/O2 during respiration in an adult male Periplaneta americana.
