Complete step-by-step answer:

An irrational number is a real number that cannot be represented as a ratio or a simple fraction.

Or an irrational number cannot be represented in the form pq,q≠0.

By definition, a surd is an irrational root of a rational number. So we know that surds are always irrational and they are always roots.

For example:

2–√ is a surd since 2 is a rational number as 2 is written as (21) and 2–√ is irrational number as 2–√ cannot represented in the form pq,q≠0.

Similarly, the cube root of 9 is also a surd since 9 is rational and the cube root of 9 is irrational.

⇒9–√3 Is an irrational number and 9 is a rational number.

On the other hand, π−−√ is not a surd because π is not a rational number it is an irrational number as π cannot be represented in the formpq,q≠0.

Thus, to answer the question, every surd is an irrational number.

But every irrational number may or may not be a surd for example π−−√

We know that every prime number is integer so it can’t be irrational. So option (B) is already rejected.

So this is the required answer.

Hence option (D) is correct.
