Choose the most appropriate prefix to complete the highlighted word in the given sentence:
The risks far ___ weigh the potential benefits of an open book examination for senior secondary students.

Correct option is A

The correct option is (a) out.

Explanation:
The sentence states that the risks are greater in magnitude or significance than the potential benefits. The word needed is outweigh, formed by adding the prefix out- to weigh. The adverb far before the blank further intensifies the comparison, meaning the risks are considerably greater than the benefits.

Correct answer – outweigh:
Outweigh means to be greater or more significant than something else in terms of importance, value, or effect.
(Hindi meaning: अधिक भारी होना / महत्त्व में बढ़कर होना)
Example: The advantages of the plan far outweigh the disadvantages.

Explanation of Other Options:

• (b) mis + weigh = misweigh – Not a standard English word; mis- implies doing something wrongly (e.g., misguide). Does not suit the context.
• (c) re + weigh = reweigh – Means to weigh again; does not convey comparison or superiority in significance.
• (d) over + weigh = overweigh – While overweigh exists in rare usage, outweigh is the standard and widely accepted term for expressing that one thing is more important or significant than another.
