Which micro-animal came back to life after being frozen for 24, 000 years in Siberian permafrost?
A
Rotifers
B
Tardigrades
C
Loricifera
D
Megaphragma
Explanation: 

Detailed explanation-1: -Scientists were able to revive a tiny, multicellular animal called a bdelloid rotifer that had been frozen in the Siberian permafrost for 24, 000 years, reports Marion Renault for the New York Times.

Detailed explanation-2: -Scientists unearthed a microscopic, multicellular animal called a bdelloid rotifer -that had been frozen in Siberia for over 24, 000 years. The worm-like creature could reproduce even after spending 24 millennia in a deep freeze of 14 degrees Fahrenheit.

Detailed explanation-3: -It’s a microscopic worm called a rotifer that was brought back to life after spending about 25, 000 years locked in the arctic permafrost. Its tale is told in the journal Current Biology. [Shmakova et al., A living bdelloid rotifer from 24, 000-year-old Arctic permafrost.]

Detailed explanation-4: -Discovery of Bdelloid Rotifer The microorganism can be found in waters around the world. This animal survived being frozen for many years through a remarkable means of cloning itself multiple times through an asexual reproduction form called parthenogenesis, according to Accuweather.

Detailed explanation-5: -The humble yet remarkably hardy bdelloid rotifer has now surprised researchers yet again-a recent study unearthed 24, 000-year-old Siberian permafrost and found living (or at least revivable) rotifers there. Surviving 24, 000 years in a deep freeze is a new record for the species.
