Which of the following statement is correct?
(1) The most vital event of sexual reproduction is formation of gametes
(2) Syngamy results in the formation of a diploid zygote
(3) In rotifers, the formation of new organism takes place via parthenogenesis
(4) In pteridophytes, syngamy occurs inside the body of the organism
Choose the correct answer from the options given below:

Correct option is B

In many terrestrial organisms, belonging to fungi, higher animals such as reptiles, birds, mammals and in a majority of plants (bryophytes, pteridophytes, gymnosperms and angiosperms), syngamy occurs inside the body of the organism, hence the process is called internal fertilization. The most vital event of sexual reproduction is perhaps the fusion of gametes. This process called syngamy results in the formation of a diploid zygote. some organisms like rotifers, honeybees and even some lizards and birds (turkey), the female gamete undergoes development to form new organisms without fertilisation. This phenomenon is called parthenogenesis.
