With cyberspace giving an opportunity to many to express themselves, the question that remains unanswered is whether their voices are heard?

(I) As cyberspace might be giving

(II) While cyberspace may have given

(III) Although cyberspace has given

“While cyberspace may have given” is the correct phrase to make the sentence grammatically correct. First of all, it is to be noted that the sentence is conditional as the second part of the sentence is dependent on the first part. When we consider options provided, option (I) can be easily eliminated as the use of “As” or “Since” is incorrect in this case (“As/Since” is generally used to express the cause of its dependent clause). Moreover, “while” is the correct usage as it means “in spite of the fact that; although”. Thus both the phrases (II) and (III) provide the grammatically correct and meaningful sentences. Hence 4 is the correct option.
