I'd say D but you could accidentally damage something more easily in the process.

[ramesh]

To remove dust and dirt you should first use a can of compressed air to blow it free. Then you should use a damp (not wet) cloth to pick up the dust and dirt. You could also use a special anti-static vacuum cleaner to remove dust and dirt from the case.

Correct Option(s):

a) A can of compressed air

Incorrect Option(s):

b) A household vacuum cleaner - You should never use a household vacuum cleaner inside a computer case as they generate a lot of static electricity.
c) A wet cloth - You should never use a wet cloth when cleaning the inside of a computer.
d) A specially treated, commercially available dusting cloth - You should not use these as most of them use static electricity to attract dust to them.
