Final answer:
A resectoscope is primarily used to resect tissue from the prostate gland. The other anatomical structures listed are not the usual targets for resection using this instrument.
Correct option is B
Step-by-step explanation:
A resectoscope is used to resect the B. prostate. A resectoscope is a surgical instrument used primarily in urology to remove tissue from the prostate. This tool is inserted through the urethra during a procedure known as transurethral resection of the prostate (TURP). The other options in the question, such as ovaries, vas deferens, and fallopian tubes, are not the typical targets for resection using a resectoscope.
For instance, fallopian tubes might be ligated surgically for sterilization, and issues with the ovaries or vas deferens are typically addressed through different surgical approaches.
