Correct option is C
The correct answer is option (c).
Explanation:
- The verb dispose is used with the preposition of.
- Therefore, the correct phrase is disposing of waste, not disposing waste.
- The word also is appropriate because the sentence is listing another function of rivers in addition to other functions.
Correct sentence (replaced segment):
Rivers also provide a means of disposing of waste, and act as a transport medium.
Why other options are incorrect:
- (a) disposing the waste is incorrect because dispose does not take a direct object without of.
- (b) No correction required is wrong because the original segment misses of.
- (d) Omits also and keeps the incorrect structure disposing waste.
Grammatical rule (English):
Dispose is followed by of: dispose of + noun.
Grammatical rule (Hindi):
Dispose के साथ of का प्रयोग अनिवार्य है: dispose of + वस्तु (किसी चीज़ का निपटान करना)।
So the correct answer is (c)
