A component has reliability function R(t) and hazard rate function h(t).

Which of the following statements is correct?

a) When h(t) = constant, the failures tend to accelerate (or the items wear out more quickly) as time increases

b) h(t) measures the tendency or rate of failure at time t, relative to (or conditioned on) the reliability at t

c) When h(t) = constant, the failures tend to deccelerate (or the durability of item increases) as time increases
