The correct answer is A. Represent the ranges of sizes in living lemurs, though extinct lemurs included larger forms.
Explanation:
The mouse lemur and the indri are two different species of lemurs, this means as all lemurs they are primates and native to Madagascar (an island in Africa). However, in terms of size the two species differ greatly, the mouse lemur is the smallest lemur existing species as they size of thee lemurs is only about 11 inches and its weight is around 30 grams; on the other hand, the indri is the biggest species of lemur as the size of these lemurs is 27 inches and their weight is around 8 kilograms. Despite this, the indri is not the biggest lemur species that has ever existed as there is evidence in the past there were lemurs as big as modern gorillas.
Since the sun is about 26,000 light-years from the centre of the milky way the sun travels at a speed of about 782,000 km per hour in a circular orbit around the centre of the milky way.
As sun itself is formed some 4.6 billion years ago the sun thus needs to speed up and this phenomenon is called as the cosmic year i.e is the amount of the time it will take the sun to reach the centre of the galaxy.
