Easy peasy, it's B) 22.2231. The string addition in the first part gives us 22.2, and the second part just concatenates 23 and 1 to give us the final result.

Haha, this is a tricky one! I'm going to guess C) 22.2,231. The first part makes sense, but the second part seems to be throwing in a random comma. Classic programming humor!

I'm going with D) 56.2. The first part of the expression adds the two strings, which should result in 22.2, and the second part adds 23.0 to that, giving the final answer 56.2.

The output is clearly B) 22.2231. The first part of the expression adds the two strings '22' and '0.2', resulting in the numeric value 22.2. The second part concatenates the integer 23 with the decimal 1, giving 23.1.

I'm not sure, but I think the answer is B) 22.2231 because the numbers are being treated as strings in the echo statement.

I agree with Samira, because the echo statement will concatenate the strings and output them as a single string.
