Answer:

Option C) 25 degrees Celsius

Step-by-step explanation:

C = 5(F – 32)/9

To find the equivalent scale in Fahrenheit, we substitute the value of F in the equation as 77.

Therefore:

C = 5(F – 32)/9

C = 5( 77 - 32 ) / 9

Simplify the brackets first, before opening it.

C = 5 ( 45) / 9

C = 5 * 5

C = 25 Degree Celsius

Option C is correct
