Pollination is the process by which plants reproduce themselves. During pollination, pollen grains must be transferred to the stigma, the end part of the plant’s reproductive organs. Some plants reproduce with abiotic pollination, meaning they spread their pollen grains without the assistance of insects or birds. Biotic pollinators require insects or birds to carry pollen from plant to plant. Plants have developed characteristics such as brightly colored petals and sweet tasting nectars to attract these creatures.
If the statements above are true, which of the following must also be true?
A. More plants reproduce by biotic pollination than by abiotic pollination.
B. Plants that reproduce abiotically rely on gusts of wind to carry their pollen grains.
C. Insects and birds are not aware that they are being used to transfer the pollen grains of plants.
D. Either birds or insects do not see exclusively in black and white.
E. Without insects and birds, plants would go extinct.

The argument is saying
Abiotic: Don't need insects or birds for pollination
Biotic needs Insects or birds for pollination. So, they attract them using brightly colored petals and sweet tasting nectars.
We have to find out a MUST be True Statement.
A. More plants reproduce by biotic pollination than by abiotic pollination. : No where this is mentioned. OFS.
B. Plants that reproduce abiotically rely on gusts of wind to carry their pollen grains. How do they reproduce, again we don't know.
C. Insects and birds are not aware that they are being used to transfer the pollen grains of plants. Whether they are aware or not, they are more focused in other things. Hence, incorrect
D. Either birds or insects do not see exclusively in black and white. Yes, plants are using colored petals. May be one of these can see black and white. So, Correct
E. Without insects and birds, plants would go extinct. Is it?? What about Abiotic ones? Incorrect

between choice B and D
choice B - Plants that reproduce abiotically rely on gusts of wind to carry their pollen grains.
THOUGH it is a fact but it is outside of the information given in the argument
choice D is correct- either insect or birds (atleast one of them) is not color blind
