Answer :

Solution :

After reading the above paragraph one can easily comprehend that a large number of people voluntarily (proceeding from the will or from one's own choice or consent) invested in small amounts for the crowd-funding, now let's go through each option one by one. Option A states that- "Funds raised through unwilling contributions on web-based platforms.", this option is incorrect because the contribution was made willingly in small amounts by a large number of peoples. Option B states that- "Funds raised through large contributions on web-based platforms.", this option is incorrect, it has been clearly mentioned in the passage that a large number of people invest small amounts. (Large contributions are mentioned nowhere in the paragraph)
