• A. 3

Answer 1

The correct option is A 3
Key: $2|3$ means $23$.
We see the stem and leaf plot of the data, the second row contains the votes as $20,22,22,28$.
The third row contains the votes as $32$.
Fourth row contains the votes as $42,43,44,45$.
The fifth row contains the votes as $51,54$.
The sixth row contains the votes as $98$.

Only $51,54$ and $98$ votes are greater than $45$ votes which are contained in the fifth and sixth row.

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