Shikha went to see __________ palmist yesterday.

Correct answer: "A"

Explanation:

Use articles according to sound and specificity:

• Use "a" before words that begin with a consonant sound (e.g., a book, a palmist).

• Use "an" before words that begin with a vowel sound (e.g., an apple, an hour).

• Use "the" when referring to a specific or known person or thing (definite reference).

The word "palmist" begins with the consonant sound /p/, and the sentence does not refer to any particular palmist already known to the speaker or listener. Therefore the indefinite article "a" is correct: "Shikha went to see a palmist yesterday."
