Double fertilisation is a process unique to Angiosperms. After the release of two male gametes by the pollen tube, in the embryo sac, one male gamete which is near the egg fuses with the egg nucleus and this called syngamy which results in the formation of a zygote. The other male gamete fuses with the secondary nucleus and this is called triple fusion which results in the formation of a triploid primary endosperm mother cell. This simultaneous occurrence of syngamy and triple fusion in the embryo sac is called double fertilisation.
So, the correct answer is option C.

Please place the items in the correct bins with explanations: Actions involving nitrogen that bacteria perform include: Nitrogen fixation: This is the process by which certain bacteria convert atmospheric nitrogen (N2) into a form that can be used by plants and other organisms. Examples of bacteria that perform nitrogen fixation include Rhizobium and Azotobacter. Nitrification: This is the process by which certain bacteria convert ammonia (NH3) into nitrite (NO2-) and then into nitrate (NO3-). Examples of bacteria that perform nitrification include Nitrosomonas and Nitrobacter. Denitrification: This is the process by which certain bacteria convert nitrate (NO3-) back into atmospheric nitrogen (N2). Examples of bacteria that perform denitrification include Pseudomonas and Paracoccus. Obligate anaerobes: These are microorganisms that can only survive and grow in the absence of oxygen. They are typically involved in denitrification. Facultative anaerobes: These are microorganisms that can survive and grow in both the presence and absence of oxygen. They can perform various nitrogen-related processes, including nitrogen fixation, nitrification, and denitrification. Microbes that oxidize inorganic compounds: These are chemolithotrophs, which obtain energy by oxidizing inorganic compounds. Some chemolithotrophs are involved in nitrification. Chemoorganotrophs: These are microorganisms that obtain energy by oxidizing organic compounds. They can also perform various nitrogen-related processes. Please drag the appropriate items to their respective bins.
