• A. $3$ students
• B. $2$ students
• C. $4$ students

Answer 1

The correct option is A $3$ students

Key: $2|3$ means $23$.
We see the stem and leaf plot of the data, the second row contains the votes as $20,22,22,28$.
Third row contains the votes as $32$.
Fourth row contains the votes as $42,43,44,45$.
Fifth row contains the votes as $51,54$.
Sixth row contains the votes as $98$.

Only $51,54and98$ votes are greater than $45$ votes which are contained in fifth and sixth row.

This means that only $3$ students received more than $45$ votes.
