While punctuating a sentence it is important to capitalize the proper nouns such as the name of a person, place or organization. It is a common rule that the initials and the first letter of a person’s name should always be capitalized. Also, one needs to separate the individual letters in the initials with a full stop, to highlight the different letters. Therefore ‘J.R.D. Tata’ would be the correct way of writing. Since options, B and D fail to capitalize the initials and the first letter of the name they are incorrect. Similarly, adjectives in a sentence are not capitalized unless they figure as the first word of a sentence or denote a title that a person possesses, for example, “Honourable Chief Minister”. Therefore the capitalizing of the ‘g’ in ‘Great’ would be wrong. Hence option C is incorrect whereas option A is correct.
