To find the total number of students attending, you simply add the number of 4th grade students to the number of 5th grade students and any other students that are mentioned if applicable.
From your information:
- Number of 4th grade students = 102
- Number of 5th grade students = 177
- Total students attending = 219
However, it seems there is a discrepancy because 102 + 177 = 279, which exceeds 219.
Assuming the number 219 refers to all students attending, the correct answer to the original question is simply the total 219.
Since the options provided are not related to this clarity, you might prefer to clarify the context or whether there are additional details required in the question.
If the concern is about verifying responses based on the provided options, we need more context or correction in the numbers. If you believe that it's confirmed that 219 is the total, then the answer should just be 219 (though it's not among the options).
If verifying the students' sum as per original context, the answer logically according to raw addition (with correction of prior understandings) might hover in the bemusement of your offerings.
