لطفا زود جواب بدید

the skin is the interface between the internal and external environments,and the exchanges of energy that affect body temperature.these exchanges between the body and the environment are the result of mechanisms such as radiation,conduction,and convection.
in a low temperature environment the amount of energy lost through convection by a person without insulating clothing,will be proportional to
a. the surface area of their body,and the difference in temperature between his body and the environment
b. the fourth power of their body temperature
c. only thr difference in temperature between their body and the environment
d. the persons height and the difference in temperature between their body and the environment

for me that this tests choice is a
because
the main result of lost of energy between environment and body without insulating clothing is the surface of their body and difference between body and environment its lucid and limpid !
good luck A.I
