What is true about $T-lymphocytes$ is mammals?

They scavenge damaged cells and cellular debris

These are produced in thyroid

There are three main types-cytotoxic $T-cells$, helper T-cells and suppressor T-cells

These originate in lymphoid tissues

Solution

The function of $T-cells$ is to provide immunity (cellular type) and not to scavenge damaged cells and cells and cell debris. These are produced in bone marrow and mature in thymus. Hence, the only true statement is that there are three types of T-cells, $i.e.$,cytotoxic, helper and suppressor.
