C) To make the emitted light colored D) To reduce the cost of the bulb
 
Answer & Explanation Answer: A) To increase the life of the bulb

Explanation:

Argon is also used to create an inert atmosphere for growing semiconductor crystals, arc welding and for processes that need protection from other kinds of atmospheric gases.
