Answer:a) a sturdy-finned, shallow-water lobe-fin whose appendages had skeletal supports similar to those of terrestrial vertebrates.
Explanation:
An ancestor - An earlier type of a species at any distant time — a progenitor.
A tetrapod is any vertebrate with four limbs. It includes any vertebrate (such as birds or snakes) that have evolved from early tetrapods — especially all members of the superclass Tetrapoda.
The presence of bones that support the appendages in Lobe – fin fish were found to be similar to the categorical skeletal supports found in the limbs of sample tetrapods. The sub class crossopterygii includes the Lobe – fin fish, which is seen as one of the recent common ancestor of living tetrapod today.
In the given case, the percent of total driver under the age of 20 are (9435/92290)*100 = 10.22%.
The percent of total male drivers are = (46021/92290)*100 = 49.87%.
Here it can be observed that the female drivers are greater in number between the age group of 20 to 59, while the male drivers are more in numbers for the individuals below the age 20 and above the age 60.
