Myxoma peritonei may occur as a consequence of rupture of which ovarian cyst ?

The correct answer is (d) Mucinous cystadenoma.

Myxoma peritonei is a rare condition where mucinous material accumulates in the peritoneal cavity, often due to the rupture of a mucinous ovarian cyst. Mucinous cystadenoma is a type of ovarian tumor that produces mucin, a thick, jelly-like substance. If a mucinous cystadenoma ruptures, the mucin can spill into the peritoneal cavity, leading to myxoma peritonei.
