The statement doesn’t make sense.

Work Step by Step

When two complex numbers represented in polar form are multiplied, then the moduli of the two numbers are multiplied and the arguments of the two numbers are added. But in this statement, it is said that the multiplication of two complex numbers in polar form is performed by first multiplying the moduli and then multiplying the arguments, which is not correct. Hence, the provided statement doesn’t make sense.
