Geometry

Question Analysis:
This question involves understanding logical syllogisms and applying deductive reasoning to geometric shapes.
The main focus is on determining a valid conclusion from the given premises.

Key Concept Explanation:
A syllogism is a form of reasoning where a conclusion is drawn from two given or assumed propositions (premises).
In this case, the premises relate properties of squares and rectangles.

Step-by-Step Solution:
Premise 1 states that all squares are rectangles.
Premise 2 states that all rectangles have four right angles.
Combining these, we conclude that all squares (being rectangles) must also have four right angles.

Option Analysis:
A) Correct: Follows logically from the premises.
B) Incorrect: Not all rectangles are squares.<...
