Answer: C

Explanation:

Correct Answer. C. Connect oneself to an anti-static mat where the computer will be placed Connecting to an anti-static mat effectively dissipates static charges, reducing the risk of ESD when handling and installing electronic components like a hard drive. This is a recommended practice in environments where electronic components are handled.

Option A is incorrect because insulating the work area with plastic sheets can actually increase the risk of static build-up.

Option B is incorrect as using tools with insulated handles protects against electrical shock but does not necessarily prevent ESD.

Option D is incorrect because while anti-static sprays can help reduce static build-up, directly grounding oneself with an anti-static mat is a more effective and controlled measure.
