Given:

If p and q are perfect squares, then √(p/q) is always a rational number.

Formula used:

If p = a2 and q = b2, where a and b are integers, then:

√(p/q) = √(a2/b2) = a/b

Calculation:

Let p = 16 (42) and q = 9 (32):

√(p/q) = √(16/9)

⇒ √(16/9) = √(42/32)

⇒ √(42/32) = 4/3

Since 4/3 is rational, the statement holds true.

∴ The correct answer is option 3).
