Correct answer
A. require presence of water for fertilization
Step-by-step solution
During fertilization ventral canal cell and the neck canal cell, along with tip of the neck disintegrate and the neck forms a canal like passage full of mucilage and some chemicals like malic acids. These chemicals attract antherozoids (chemotactic movement of antherozoids) and one of the male gametes fuses with the oospore forming a diploid oospore. Water is essential for this process.
