Pratham Dave from GNS, Bangalore

I agree with Shreya, They are talking about pollination and not dispersal. Pollination and dispersal are two different terms. If I am correct, Pollination by water occurs only in aquatic and semi-aquatic plants.

Actually, the question should be "Select the plants that are NOT pollinated by water". Vallisneria and Zostera are two plants that are aquatic, so by default their pollination is going to happen through water. All the other options are grown on land and their pollination happens through other agents. I am disappointed with SOFs repetitive errors in several worksheets and ask them to PLEASE, PLEASE rectify this error and all other errors IMMEDIATELY WITHOUT ANY DELAY.

Both options a and b are not correct as statements 1 and 4 are wrong in my opinion. In fact none of them are correct since statement 2 is the only correct statement.
