The problem asks which binary number represents the ASCII value of "H" given that "G" is represented by $1000111_2$.

1. Problem Description

The problem asks which binary number represents the ASCII value of "H" given that "G" is represented by $1000111_2$.

2. Solution Steps

Since "H" is the next letter in the alphabet after "G", its ASCII value will be one greater than the ASCII value of "G". Therefore, we need to add 1 to the binary representation of "G", which is $1000111_2$.

$1000111_2 + 1_2 = 1001000_2$

We perform binary addition:

1000111

+ 1

----------

1001000

3. Final Answer

The binary representation of "H" is $1001000_2$. The correct answer is (2).
