What might be a strategic approach to tackling multiple-choice questions in the exam?

Eliminating obviously incorrect answers first is a strategic approach that enhances the likelihood of selecting the correct option. By narrowing down the choices, a test-taker can focus on the remaining answers that are more plausible. This process helps to reduce the number of possible answers and can potentially lead to the correct choice, especially in instances where the test-taker may not feel entirely confident about their knowledge of the subject.

This method capitalizes on deductive reasoning, allowing the candidate to engage in a more analytical approach rather than relying on chance. It also helps to build confidence, as the candidate can make educated guesses based on their understanding, rather than feeling overwhelmed by the full breadth of choices present.

The other options do not offer as effective a strategy. Guessing can lead to random selection without any basis, often resulting in lower accuracy. Reading all the choices before the question can be a waste of time and might lead to confusion, as the candidate might fixate on options that are not relevant to the question. Marking all answers as 'C' lacks logic and is generally based on a misconception about patterns in multiple-choice tests, which is not a valid strategy for improving performance.
