b. ADH
c. Oxytocin
d. ACTH

Dear student,

The correct option is B - 


The concentration of urine is controlled by the hormone ADH - Anti Diuretic Hormone
The ADH is released from the posterior pituitary and generally decreases the urine concentration. It is released into the body during standing posture, enjoyment etc.
