Choose the option that best fills in the blank:
______ are born with a silver spoon in their mouths.
a) this
b) one
c) some
d) that

Hint:The subject has to match the other verbs in the sentence, and their singularity or plurality must be maintained. Try to identify which subjects don’t fit in the given sentence.

Complete answer:
In English, grammar rules are followed strictly as they can completely change the meaning of the sentence. So, tenses and verbs become very important in this language.
In order for a sentence to be grammatically correct, it has to have the following:
First letter and proper nouns must be capitalized.
The subject should match the verb, in number.
The tense should also be relevant to the sentence.
It should be properly punctuated.
It should have each part of the speech arranged properly.

Now, let’s look at the given options:

a) this - The word ‘this’ is a singular subject. The verb in our given sentence is the plural verb ‘are’. The subject and the verb do not match. This is not the required answer. So, this is an incorrect option.
b) one - The word ‘one’ is also a singular subject. The verb in our given sentence is the plural verb ‘are’. The subject and the verb do not match. This is not the required answer. So, this is an incorrect option.
c) some - The word ‘some’ is a plural subject. The verb in our given sentence is the plural verb ‘are’. The subject and verb are both plurals. They match. This is the required answer. So, this is the correct option.
d) that - The word ‘that’ is also a singular subject. The verb in our given sentence is the plural verb ‘are’. The subject and the verb do not match. This is not the required answer. So, this is an incorrect option.

Note:
Dissect the sentence and go through parts of the sentence separately, and see if there are any subjects to be worth noting. Then, choose the appropriate option accordingly.
