B) Nucleus
C) Peroxisomes
D) Chromosomes

Answer 1

Answer:(C) Peroxisomes

Explanation:

Answer 2

DNA remains absent in Peroxisomes (option-C).

• Chloroplast is a semi-autonomous organelle, which means it has its own DNA to produce some of its functional proteins, as well as some proteins which are transcribed from the cell's genome, are targeted to it.
• The nucleus is a part of the cell which contains genetic material such as DNA or RNA ( in some viral cells). The DNA can be single-stranded or double-stranded.
• Peroxisomes are the cell organelles, which are basically involved in the metabolism of lipids and detoxification of reactive oxygen species (ROS) formed inside a cell. These do not have their own DNA.
• Chromosomes are the bundles of highly coiled DNA and in a microscopic view, these appear as thread-like structures, and present in the nucleus of a cell.
