C. Wear-out
D. Time

Explanation: Time is the horizontal dimension on which the bathtub curve is built and not the phase.

A. time
B. efficiency
C. quality
D. speed

Explanation: Software Reliability mainly concerned with the time component. It can be seen in various models like Basic Execution Time Model and Logarithmic Poisson Execution Time Model.

A. Reliability
B. Efficiency
