why do you think using a person's own cell to make a new organ or tissue for them will increase the chance that their body will accept the transplant?

In my personal opinion, I think this is possible because your body already knows the cell. It is already familiar with it.

Explanation:

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
