I didn’t like Maths. I had to study Algorithms.

Combine the above sentence with a conjunction that expresses a contrast:
A) Although I didn’t like Maths, I had to study Algorithms.
B) I didn’t like Maths in spite of that I had to study Algorithms.
C) I didn’t like Maths, so I had to study Algorithms.
D) I didn’t like Maths and I had to study Algorithms.

Hint:First of all, understand the sentences properly. Analyze and choose the right conjunction according to the condition stated in the question. Choose the correct answer by ruling out the incorrect answer one by one.

Complete answer:
Option A) Although I didn’t like Maths, I had to study Algorithms – is the right answer as the condition stated in the question is to express a contrast.
Option B) I didn’t like Maths in spite of that I had to study Algorithms – is an incorrect answer as it is not fulfilling the condition stated in the question.
Option C) I didn’t like Maths, so I had to study Algorithms - is an incorrect answer as it is not fulfilling the condition stated in the question.
Option D) I didn’t like Maths and I had to study Algorithms - is an incorrect answer as it is not fulfilling the condition stated in the question.
Hence the correct answer is option ‘A'.

Note: Conjunction is a word that is used to connect two sentences. Common examples of conjunctions are and, but, if, so, etc. Sentences joined by conjunctions should share the same structure. Conjunctions are of three types. They are: coordinating, subordinating and correlative conjunctions.
Coordinating conjunctions are words which link two sentences which are independent of each other.
 Example: She came late. She had food.
                   She came late and had food.
‘And’ is the conjunction here.

Subordinating conjunctions are words which link two sentences which are dependent over each other. They express contrast.
Example: She doesn’t like tea. She had to drink it.
                  Although she doesn’t like tea, she had to drink it.
‘Although’ is the conjunction here.
Correlative conjunctions are paired conjunctions. They link sentences as a pair.
Example: I don’t like him. I don’t like his attitude.
                 I neither like him nor his attitude.
‘Nor - neither’ are the paired conjunctions here.

Since ‘although’ is a subordinating conjunction and expresses contrast, option (A) is the right answer. Option (B) is incorrect as ‘in spite of’ is considered a preposition and not a conjunction. Option (C) doesn’t give the right meaning and option (D) doesn’t express contrast.
