Correct Answer - B
Ans. is 'B' i.e., Aponeurosis of three muscles including External
Oblique, Internal Oblique, and Transversus Abdominis

The anterior wall just above the symphysis pubis (area below the
arcuate line) → is formed by aponeurosis of all three muscles
(external oblique, internal oblique, transversus abdominis).
Three aponeurotic layers forming rectus sheath of both sides
interlace with each other to form a tendinous raphe, Linea alba. It
extends from the xiphoid process to pubic symphysis.
Linea alba is narrow and indistinct below the umbilicus, as two recti
lie in close contact. Linea alba broadens out above the level of the umbilicus.

Correct Answer - B
Ans. is 'b' i.e., Medulla [Ref Quantitative Human physiology : An introduction p. 327]
It has not been mentioned in any textbook.
But according to the above mentioned reference nucleus
fasciculatus is the other name of nucleus cuneatus.
"The sensory fibers of dorsal column travel in tracts, fasciculus
gracilis and fasciculus Cuneatus in the Cord and these fibers make
synapses with second order neurons in the nucleus gracilis and the nucleus fasciculatus". — Quantitative Human physiology.
Nucleus gracilis and nucleus fasciculus are found in the medulla.

Correct Answer - C
The ovarian artery arises from the abdominal part of the aorta at the
level of the first lumbar vertebra. The artery is long and slender and
passes downward and laterally behind the peritoneum. It crosses the external iliac artery at the pelvic inlet and enters the suspensory
ligament of the ovary.
It then passes into the broad ligament and enters the ovary by way of the mesovarium.
