What kind of format this, it is a roman numeral, arabic form or alphanumeric form and why?

alphanumeric form

Explanation:

Considering the image shown in the question the right answer is ALPHANUMERIC FORMAT.

This is because the Alphanumeric format is a writing pattern that has a combination of alphabet and numeral or numbers as characters. And the image is written in the alphabet characters hence it is in Alphanumeric format.

It is not Numeric format because the image is not written in Numeral or number characters.

It is also not Arabic format because it is not written from left to right and at the same time not written in Arabic lamguage

the answer should be the first one. "many people find his lyrics very moving."

it by far makes the most grammatical sense and is very objective, removing any first person from the original sentence and keeping with the sentence fluency.

comfortable
