Step 1: Analyze the question's premise.
The ASCII standard assigns numerical values to single characters. The string "10" is composed of two separate characters: '1' and '0'. There is no single ASCII value for "10".
Step 2: Interpret the likely intent of the question.
The question most likely contains a typo and is asking for the ASCII value of the character '0'.
The ASCII value for the character '0' is 48.
The ASCII value for the character '1' is 49.
Given the options, 48 is the only one that corresponds to a character in the string "10".
