(d)Ostrich

Answer 1

Hint: Struthio is a genus of birds in the order of Struthioniformes. It is part of the Palaeognathae infraclass, a large group of flightless birds that includes emus, rheas, and kiwis, also known as ratites.

Complete answer:
Struthio camelus (Ostrich) is a large, flightless bird found only in Africa. He's the biggest living bird. The length of the ostrich egg is about 150 mm (6 inches) by 125 mm (5 inches) in diameter, and the world's largest egg is about 1.35 kg (3 pounds). The largest egg weighed 2,589 kg on record and was laid in Borlange, Sweden, by an ostrich.
The largest of any living bird is the egg of the ostrich (genus Struthio). The shell has a long history of use as a container and for decorative artwork by humans. Eggs are not consumed regularly.

Additional Information: Elephants mature slowly and have a long lifetime of reproduction. At approximately four to five-year intervals, female elephants give birth to single calves (although twins have been recorded) and have been reported with up to 12 offspring per lifetime, although this number is unusual.
Dinosaurs did not give birth in the way that mammals do, to live young. Like most reptiles, and like birds, a number of eggs were laid by female dinosaurs. These eggs were usually placed in a nest of twigs and leaves, or in a hole in the soil or sand that the woman had dug.
Their calves develop within their mothers and are born through live births since whales are mammals. Calves can first grow fins during birth. The size of the whale calf may depend on the size of the mother, but you should assume it to be around 1⁄4 of the mother's length in general.
So, the correct answer is ‘Ostrich’.

Note: Whales are marine animals that may be more similar than you would expect to humans. Both humans and whales require oxygen to breathe, are warm-blooded, and give birth without eggs being laid. A baby whale has a cord inside its mother that binds mother and baby, just as humans have.
