Concept:
Mode is the observation which occurs most frequently in a data set.
Step 1: Find mode of each data set.
For each data set, count the frequency of each value. The value with maximum frequency is the mode.
Step 2: Compare the modes.
After finding modes of all data sets \(A,B,C,D,E\), arrange them in increasing order.
Step 3: Final order.
The increasing order on the basis of mode is:
\[
E,D,A,B,C
\]
\[
\therefore \text{Correct Answer is (C)}
\]
