• A. Lingual and submandibular unite to form the internal jugular.
• B. Musculo-cutaneous and brachial unite to form the subclavian.
• C. The ventral abdominal vein drains into the posterior vena cava.
• D. The pelvic veins unite to form the renal portal vein.

Answer 1

Answer: (B)

Musculo-cutaneous and brachial unite to form the subclavian.

Lingual and submandibular unite to form the external jugular and not internal.
The ventral abdominal vein joins the hepatic portal vein.
The pelvic veins unite to form the anterior abdominal vein.
The subclavian, which is formed by the union of two veins, namely a brachial vein brings blood from the forelimb and a long musculocutaneous vein bring blood from the skin and muscles of the body wall from the major part of trunk region.
Thus, the correct answer is option (B).
