Fill in the blanks with appropriate Articles:

You are ____ gem of _____ person.

a, a

The correct answer is Option (3) → a, a

• "a gem": The word "gem" starts with a consonant sound. When a noun begins with a consonant sound, we generally use the indefinite article "a" before it. Think of it as saying "one gem."

• "a person": Similarly, the word "person" begins with a consonant sound. So, we use the indefinite article "a" to indicate "one person."

The sentence is expressing that you are a very valuable and excellent individual (a gem) and also one among the category of people (a person).
