Answer 1

They can apply to more than one animal.For example,if you say you are looking for a baby calf,they might think you are talking about many different things.

Answer 2

Answer: Option 'D' is correct.

Step-by-step explanation:

Common names are not always useful to biologists because they can apply to more than one animal.

Like common name does not tell about the family of species.

For eg : House cat and lion are common names given to them but using scientific names we came to know that they belongs to same family "Felidae".

And calf is common name apply to baby of cow or bull.

But it does not clarify the actual name of whose baby it is.

Hence, Option 'D' is correct.
