The correct option is A entomophily
Entomophily is the type of pollination which uses biotic agents like moths and insects as the pollinating agents. So the plants require attractants like colourful petals and scents to attract the insects. Rewards like the nectar also attracts the pollinators.
Hydrophily and anemophily employs abiotic pollinating agents and hence do not need any attractants and rewards.
Artificial hybridization is performed by conscious choice so do not require any rewards or attractants.
