Answer:
No Sharma is an honest person.
Step-by-step explanation:
Articles are "a, an, the" and are used according to their nature like a vowel or a consonant, singular or plural, or definite or an indefinite noun, etc.
In the given sentence, the word to be used is either one of the three articles. And in looking at the word "honest", the letter "h" which starts the word is a consonant. This, by rules of articles, will require the use of "a". But, as the "h" is silent in the sound of "honest", then the use of the "a" is invalid. Judging by the pronunciation, the first sound from the word "honest" is "o" where the word is pronounced as "onest".
Thus, the correct article to be used is "an".
