Question

Given below sentence. A part of each sentence is underlined which may contain an error. Replace the underlined part with the right choice
Of these two books which is the least costly

• A. which one is the least costly
• B. which is least costly one
• C. which is less costly
• D. which one less cost

Answer 1

The Correct Option is A

To solve this problem, we need to correctly replace the underlined part of the sentence with the grammatically correct choice from the given options. The original sentence provided is:

"Of these two books which is the least costly"

Let's analyze the options:

1. which one is the least costly: This option is grammatically correct and properly compares two items, which requires using the comparative form "least." The phrase "which one" helps specify one of the two books, making this option the correct choice.
2. which is least costly one: This option is incorrect because "least costly one" is unusually structured and lacks a definitive subject, which is simple and clear in comparative questions.
3. which is less costly: While "less costly" is comparative, it does not use "which one" to specify among the two items. This makes the sentence less clear compared to option 1.
4. which one less cost: This option is grammatically incorrect as it lacks proper comparative form and syntax.

The most appropriate and grammatically correct choice is "which one is the least costly". This option correctly uses the article "the" with the superlative "least" to compare two items specifically, completing the sentence clearly and effectively.

Therefore, the correct sentence is:

"Of these two books, which one is the least costly?"
