Concept: To find the correct option for a given problem, you need to understand the concept of unary operations and find the minimum number of operands required for the operation specified by the option. B. The additive operation requires two operands,

. Where A and B are the operands that use this statement to approach the solution of the question.
Let's discover the operands utilised in addition.
We understand that during addition, we are able to`t practice this operation if we've best 1 operand. We want not less than 2 operands to perform on. For example, if we've various 2 we are able to use the extra operation till we get one extra variety.
Since unary operation operates with best 1 operand, consequently, dependency isn't always a unary operation.
For multiplication operations we understand that we want minimal 2 operands to perform the operation for instance if we simply have various 6 we are able to use the multiplication operation in this situation to apply the operations we can want one extra variety.
Since multiplication calls for 2 operands to perform, consequently multiplication isn't always a unary operation.
For rectangular root operation, we want minimal 1 operand to perform on, for instance, let's take various four we must use the rectangular root operation so we are able to practice this operation even we best have four for that reason the rectangular root of four might be four

Since rectangular root operation calls for the best one operand or variety to perform the operation, consequently, the rectangular root is a unary operation.
Hence, the correct answer is option (3).
