Hint: The animal that has the longest gestation period is also called ‘ship of the desert’. These animals will have a fatty deposit in its hump that helps them to withstand the desert conditions.

Complete answer:
The camel has an average gestation period of 13-14 months or 410 days. A cow's gestation period ranges from 279-287 days and typically is 283 days. A dog's gestation period usually ranges from 58-68 days. A rat's gestation period ranges from 21-23 days (rarely 26 days).
The word camel derives from ‘kremal’ in Greek. From ancient times, the camel is a significant component of the desert ecosystem and is known as the ‘ship of the desert’. Human beings depend on this animal not only for meat, milk, and hide but also as one of the most significant modes of transportation in the desert, which has risen to 10,30,000 million, almost 6-8% of the total population of camels. Camels come with 70 chromosomes. Camels have no sweat glands and can withstand heat daytime of 49oC to 50oC and night time of 30oC. Camels are a seasonal breeder and their reproduction is different from that of other livestock as both males and females during the breeding season heat up.
At an age of 3-4 years, the females undergo while males at the age of 4-5 years. The male emits a black pigment from his pole gland (skin gland) which will help them to attract the females during the heat period. In camels, the gestation period is 390 days with an average birth weight of 35-40 Kgs. Adult camels weigh between 450-750 kg.
So, the correct answer is, ‘Camels’.

Note: Elephants have the longest mammalian gestation period. The pregnancies of those gentle giants last for more than a year and a half. An elephant's mean gestation period is approximately 640 to 660 days or approximately 95 weeks.
