The ability of your body's immune system to distinguish between your cells
and bacteria depends upon
a) selective transport.
c) chromosomes.
b) cell surface markers.
d) the type of invading bacteria.

The correct option is cell surface markers.

Explanation:

The immune cells of our body detect foreign particles and generate responses so that our body can get rid of them. The foreign particles are often termed as antigens.

The immune cells such as antibodies possess cell surface receptors which detect the foreign objects or antigens. When the cell surface receptors detect any antigen they immediately recognize that a foreign particle has invaded the body and they then identify it and start to generate response.

youre right there are
