Statement-I : Only a small proportion of plants utilize abiotic agents such wind and water for pollination
Statement-II : The encounter between pollen grains and the stigma is a random event in both wind and water pollination, due to the unpredictable nature of these abiotic pollination agents.
Select the correct option: 

Statement I is true. While some plants rely on abiotic agents like wind and water for pollination (anemophily and hydrophily, respectively), the majority of flowering plants employ biotic agents like insects, birds, and animals for pollination.

Statement II is also true. In wind and water pollination, the movement of pollen grains is not directed towards specific flowers or stigmas, unlike the directed movement seen in biotic pollination (e.g., by insects). Instead, pollen grains are carried by the wind or water currents and deposited randomly on stigmas. Therefore, the encounter between pollen grains and stigmas in wind and water pollination can be considered a random event due to the unpredictable nature of these abiotic pollination agents.
