To find the percentage of all students who prefer hot dogs, we need to divide the number of students who prefer hot dogs by the total number of students and then multiply by 100.
The number of students who prefer hot dogs is 55, and the total number of students is 200.
Therefore, the percentage of all students who prefer hot dogs is (55/200) x 100 = 27.5%.
Thus, the correct answer is B. 27.5%.
