Answer 1

Hint: Unisexual organisms are the type of organisms that consists of either of the reproductive organs, it may be male or female.The unisexual organisms shows the properties of sexual dimorphism.

Complete answer:
The unisexual organisms comprises of either have male reproductive organs or female reproductive organs, hence they are distinguished amongst the same groups. Humans are animals that exhibit unisexuality. On the other hand, the organisms which do have distinguished reproductive organs and both (male and female) are the reproductive organs are present, they are called as bisexual. Reptiles such as lizards show the properties of bisexuality. In this case, no specific reproductive organs are present in the organisms rather, both the reproductive organs exist in the same species. In the angiosperm species, the conditions of unisexuality are also referred to as diclinous or incomplete. In most of the animal species the sexes have been observed to be separate i.e. either male or female. For instance humans, dogs, the dogs, humans, tiger etc. are the examples of unisexual animals. Bisexual organisms shows the behavior of romantic or sexual attractions, towards both the females and males simultaneously. This behavior could also be well-defined sexual or romantic behavior towards the people of any gender individuality. Human beings with true hermaphroditism actually do not exist, but humans with pseudohermaphroditism exist. Pseudohermaphroditism is a case where an individual comprises both the external genital organs i.e. male and female both.

Hence, the correct answer is option (A)

Note: In human beings, the stage of bisexual or intersex occurs mainly due to different types of genetic circumstances. For instance, a bisexual person is developed if two fertilized eggs fuses with each other and give rise to a zygote having one Y chromosome and two X chromosomes.
