The correct option to fill in the blanks in the sentence “I can’t mind the light. I don’t know … about electricity.” is C. Anything. So, the completed sentence is: “I can’t mind the light. I don’t know anything about electricity.”

Here’s why:

• A. Something: This option is incorrect because “something” is used in affirmative sentences, not in negative sentences like this one.

• B. Nothing: This option is incorrect because we already have a negative in the sentence (“don’t know”). We don’t usually use “nothing” after “don’t know”, we use “anything”.

• C. Anything: This is the correct option. “Anything” is used in negative sentences or questions. In this context, it means that the speaker has no knowledge about electricity.

• D. Nobody: This option is incorrect because “nobody” is used to refer to people, not things or concepts like electricity.

• E. Anybody: This option is incorrect because “anybody” is also used to refer to people, not things or concepts like electricity.
