Answer:
A). Improving one's reading skills requires a lot of effort; it also takes time.
Explanation:
As per the question, option A i.e. 'Improving one's reading skills requires a lot of effort; it also takes time' exemplifies the sentence that is correct as it is appropriately punctuated. It correctly employs semicolon(;) to join the two independent clauses to form a correct compound sentence. Option B is incorrect as it contains a comma splice where a comma(,) is mistakenly used to join two independent clauses. While option C is wrong as it demonstrates a run-on sentence where two independent clauses are linked together without using appropriate punctuation or coordinating conjunction. Thus, option A is the correct answer.
