Answer

Explanation:

Step1: Analyze initial cost

Compare the cost per bulb: conventional bulb ($0.50) < compact fluorescent ($1.50) < LED lights ($2.50). So conventional bulb has the lowest initial cost.

Step2: Analyze energy consumption

Compare power consumed per bulb: LED lights (8 watts) < compact fluorescent (15 watts) < conventional bulb (60 watts). So LED lights have the lowest energy consumption. Since no single bulb has both the lowest initial cost (conventional) and lowest energy consumption (LED), option A is correct.

Answer:

A. No lighting choice can provide both objectives.
