Question Analysis:
This question involves applying the Law of Detachment to the properties of a rhombus.
The main focus is on understanding the relationship between a rhombus and its diagonals.

Key Concept Explanation:
The Law of Detachment states that if a conditional statement ("If P, then Q") is true, and P is true, then Q must also be true.

Step-by-Step Solution:
The conditional statement is: "If a quadrilateral is a rhombus, then its diagonals are perpendicular."
The premise is: "Quadrilateral ABCD is a rhombus."
By the Law of Detachment, the conclusion is: "Quadrilateral ABCD has diagonals that are perpendicular."

Option Analysis:
A) Correct. This directly follows the Law of Detachment.
B) Incorrect. A rhombus does not necessarily...
