Answer 1

The correct option is C $4$

• Species is defined as the group of organisms that are capable of interbreeding and produce fertile offspring.
• Monkey, Horse, Donkey and Blue-green algae all are examples of different species based on this definition.
• Mule is a product of interspecific hybridisation incapable of interbreeding as it is sterile.
• So, the correct option is '4'.
