Answer 1

The correct option is D 20

All dog breeds are of the same species, yet they age at very different rates. There is variation because of :
a. Size - The larger the dog is, the less it will live.
b. Gender - Generally, female dogs tend to live slightly more than male.
c. Health Issues in purebred - Purebred dogs have more health issues, which cut upon their life-spans.
So, the dog's life span varies and on an average, the dog's life span is around 20 years.
Thus, the correct answer is option (D).
