Given a temperature value of -90.75 degrees, which of the following represents the floor and ceiling values respectively?

Correct option is C

To determine the floor and ceiling values of -90.75 degrees:
1. Floor Function:
· The floor function rounds down to the nearest integer.
· For -90.75, the largest integer less than or equal to -90.75 is -91.
· Hence, the floor of -90.75 is -91.
2. Ceiling Function:
· The ceiling function rounds up to the nearest integer.
· For -90.75, the smallest integer greater than or equal to -90.75 is -90.
