We use an apostrophe to show possession or belonging. We add an apostrophe and an ‘s’ to singular nouns for the same reason. In the given sentence, ‘Rajan’s father’ would be the right way to express possession. Therefore, option D is incorrect. On the other hand, while punctuating a sentence it is important to capitalize the proper nouns such as the name of a person, place or organization. In the given sentence, ‘Netherland’ is the name of a country and therefore the first letter of the name has to be capitalized. Therefore option C is correct, whereas option B is incorrect. Further ‘Netherland’ is a single unit, i.e. one name; therefore we should not capitalize the ‘l’ in 'lands' which is in the middle of the name. Thus option A is incorrect.
