The variable is continuouscontinuous because it isis countable. B. The variable is continuouscontinuous because it is notis not countable. C. The variable is discretediscrete because it is notis not countable. D. The variable is discretediscrete because it isis countable.

Answer 1

Answer: Option 'D' is correct.

Step-by-step explanation:

Since we know that

Discrete variable are those variable which takes only a finite number of values.

Continuous variable are those variable which takes the range in between any two observed value.

Here our question is :

Length of a nail.

Length of a nail takes only a finite number of values, so it is considered as "Discrete variable".

It is discrete because it is countable.

Hence, Option 'D' is correct.
