The following sentence has been divided into parts. One of them contains an error. Select the part that contains the error from the given options.
Mr. Thomas / is going / to buy / horse.

Correct option is D

The error lies in the segment "horse."
· The noun "horse" is a singular countable noun, and it must be preceded by an article. In this context, the appropriate indefinite article is "a" because "horse" begins with a consonant sound.
Correct sentence: Mr. Thomas is going to buy a horse.
· Grammatical Rule Used: Singular countable nouns must be preceded by an article ( a, an, or the). Use "a" before words that start with a consonant sound, and "an" before words that start with a vowel sound. In this sentence, "horse" is singular and countable, so it needs "a."
· Explanation in Hindi: गिनने योग्य एकवचन संज्ञा ("horse") के पहले "a," "an," या "the" जैसे लेखों का प्रयोग अनिवार्य होता है। चूंकि "horse" का उच्चारण व्यंजन ध्वनि से शुरू होता है, इसलिए "a" का उपयोग करना सही है।
