The true statements about he T cell receptors are 1, 2 and 4.
T cell receptors are the molecules found on the surface of the T lymphocytes. V(D)J recombination is the unique mechanism of genetic recombination that occurs only in the lymphocytes during the early stages of T and B cell maturation resulting in the T cell receptors. They recognize antigen fragments bound to MHC molecules. Majority of the T cell receptors consists of an alpha chain and a beta chain and a few with gamma and delta chains. Each chain is composed of a variable and a constant region. Within these chains are the complementary determining regions (CDRs) which determine the antigen to which the T cell receptor will bind.

Answer: a. precipitation (rain), person, wastewater, clouds, precipitation(rain).
Water cycle also known as hydrological cycle describes how water evaporates from the water body or surface of the earth, rises in the atmosphere as water vapor which forms clouds, clouds condenses in the form of rain, hence water comes back in the water body or earth surface.
Here, precipitation will result in accumulation of water on earth or water body, this water is utilized by person, the water is then converted into wastewater, the cloud formation takes place when water evaporates from waste water, these clouds condenses to cause precipitation.
