What will the expression `len("Hello")` return?

• A. 4
• B. 5
• C. 6
• D. Length of the string is not defined

Answer: (B)

The expression `len("Hello")` returns 5 because the `len()` function in Python calculates the number of characters in a given string. In this case, the string "Hello" consists of five characters: 'H', 'e', 'l', 'l', and 'o'. Thus, applying the `len()` function to this string provides the accurate length, which is 5. The other options do not correctly represent the character count in the string "Hello", as they suggest lengths that are either too short or undefined.
