Answer: The correct option is (D) 24.89.
Step-by-step explanation: We are given to convert 76.8° F to Celsius scale.
We know that
the formula for the conversion of Fahrenheit to Celsius scale is given by
\(T_c\\\\=(T_f-32)\times\dfrac{5}{9}.\)
For the given temperature,
\(T_f=76.8^\circ~F.\)
Therefore, the required temperature on Celsius scale will be
\(T_c\\\\=(T_f-32)\times\dfrac{5}{9}\\\\\\=(76.8-32)\times\dfrac{5}{9}\\\\\\=44.8\times\dfrac{5}{9}\\\\=24.89.\)
Thus,
76.8° F = 24.89° C.
Option (D) is CORRECT.
