Answer:
The correct answer will be option-A muscle cell.
Step-by-step explanation:
Nanoscales are the structures less than 100 nm in length which is considered a billionth of a meter scale. The nanoscales lead to the formation of a new field of study called nanotechnology which finds its use in all perspectives of science.
In the given question, the nanoscale objects are enzymes (3-7) nm) length, the water molecule (0.275 nm), and xenon atom. Since the muscle cell length is usually measured in mm(1-40 mm)
Thus, option-A is the correct answer.
