The prostate gland blocks the bladder. D. The prostate gland surrounds the bladder neck and the urethra.

B. The prostate gland presses on the urethra

Explanation:

Benign prostatic hyperplasia (BPH) is caused by the proliferation of prostatic cells, which leads to the inflammation of this gland, squeezing the urethra (i.e., the tube where urine passes) and ultimately reducing the flow of urine. BPH is a chronic condition progressive with age, thereby it is associated with old men. Although in principle BPH isn't dangerous, high pressure on the urethra may lead to incomplete emptying bladder and infections in the urinary tract.
