While reading for comprehension, we understand that some pairs are examples of homograph. Which one of the following is a homograph?

The correct answer is lead [metal]/lead [give direction].

Understanding Homographs:

A homograph is a word that shares the exact same spelling as another word, but has a different meaning (and often a different pronunciation).

Analyzing the Options:

1. lead [metal] / lead [give direction]: Both words are spelled identically as "L-E-A-D". One refers to the heavy metal element (pronounced /led/), while the other refers to guiding or directing someone (pronounced /liːd/). Since they share the same spelling but have different meanings and pronunciations, this pair represents homographs.

2. warm / tepid: These are synonyms with different spellings.

3. lead [give direction] / dead [mortal]: These are different words with different spellings that happen to rhyme (near rhymes).

4. mail [post] / male [gender]: These words sound the same but have different spellings ("mail" vs. "male"). Therefore, they are homophones, not homographs.

Thus, lead [metal]/lead [give direction] is the correct example of a homograph.
