Identify the segment that contains a grammatical error. If there is no error, select 'No error'.

Correct option is C

Option (c) contains an error.
The correct sentence should be:
"My teacher said to me that all that glitters is not gold."
Explanation:
· The phrase "All that glitters is not gold" is a well-known proverb.
· The verb "is" should be used instead of "was" because the sentence expresses a general truth.
Grammatical rule used: Present tense is used for universal truths, proverbs, and scientific facts.
Example:
· Water boils at 100°C. (Not "boiled")
· Honesty is the best policy.
Explanation of the rule in Hindi:
सामान्य सत्य या कहावतों के लिए वाक्य को वर्तमान काल (Present Tense) में लिखा जाता है। इसलिए "was" के स्थान पर "is" सही उत्तर है।
