Given below are two statements:

Statement I: Tablet computers have touch screens.
Statement II: A tablet computer does not have a keyboard.
In light of the above statements, choose the correct answer from the options given below.

The correct option is: Both A and R are true and R is the correct explanation of A.

Explanation:
Let us analyze the two statements provided in the question, keeping in mind that they are referred to as "A" (Statement I) and "R" (Statement II) in the given options:
• Statement I (A): "Tablet computers have touch screens."
This statement is true. The defining feature of a tablet computer is its touch-screen interface, which allows users to interact directly with the screen using a finger or a stylus instead of relying on a physical keyboard and mouse.
• Statement II (R): "A tablet computer does not have a keyboard."
This statement is also true in the context of standard built-in hardware. Unlike laptops or desktop computers, tablet computers do not come with an integrated, permanently attached physical keyboard. Instead, they rely on virtual, on-screen keyboards for text input, though external physical keyboards can be connected as accessories.
• Relationship between A and R:
Statement II (R) explains why Statement I (A) is necessary. Because a tablet computer does not have a physical keyboard, it must utilize a touch screen to allow users to input commands, type, and navigate the operating system. Therefore, R is the correct explanation of A.
