Answer :

To determine the result of the given line of code, follow these steps:

1. Identify the operation: The given line performs the concatenation of two strings using the "+" operator.
2. Understand concatenation in strings: In Python, the "+" operator, when used with strings, concatenates them, meaning it joins them together without any spaces unless explicitly added.
3. Analyze the given strings: The strings to be concatenated are "one" and "day".
4. Perform the concatenation: When the strings "one" and "day" are concatenated, the result becomes "oneday".

So, the correct result for the given line of code is:

oneday

Therefore, the correct answer in the multiple choice options is:

oneday
