Solve the problem.A biologist controls the humidity H (as a percentage) inside a terrarium. From an initial humidity level of 0%, she allows the humidity in the terrarium to increase by 1% per hour for the next 6 hours. After the 6th hour, she allows the terrarium to dry out (lose humidity) at the rate of 10% per hour. The humidity function H is defined byH(t) = Find k such that H is continuous at t = 24. Then explain why H must be continuous at t = 6 hours.

A. k = 186; H must be continuous at t = 6 hours because time changes continuously.
B. k = 66; H must be continuous at t = 6 hours because the humidity level changes continuously.
C. k = 54; H must be continuous at t = 6 hours because the humidity level changes continuously.
D. k = 174; H must be continuous at t = 6 hours because time changes continuously.
