Question

Which type of cell contains DNA enclosed in a nucleus?
A) centriole
B) eukaryote
C) plasmid
D) prokaryote

Answer 1

The answer is B. A eukaryotic cell's nucleus contains the DNA or the genetic material of the cell. The DNA  has the necessary information for the cell's construction and the control of the synthesis tasks done by the cell. The nucleus is protected by the nuclear membrane. It surrounds the nucleus with a membrane with many pores.

Answer 2

Answer: The correct answer is-

B) Eukaryote.

Eukaryotes ( with true nucleus) are those organisms that contain a well defined nucleus, which contains the genetic material ( DNA) of life forms. Also, they contain membrane bound sub-cellular compartments ( called as cell organelles) such as mitochondria, endoplasmic reticulum, golgi complex etc.

Example of eukaryotes- Plant and animal cell.
