What does it mean if a computer's main memory is volatile?

Answer and explanation

Correct answer: Its contents are lost when power is switched off

The governing concept is volatility of memory. Volatile main memory, normally represented by RAM, needs continuous electrical power to retain its current contents. When the computer is switched off or loses power, unsaved information in that memory is generally lost, making option B correct. Volatile does not mean unchanging, internet-only, or limited to pictures; therefore options A, C, and D confuse volatility with unrelated properties.
