Final answer:
Shareholders in a public corporation can vote by attending meetings, being informed through financial reports, and using proxy voting, with the correct answer being 'All of the above'.
Step-by-step explanation:
Shareholders in a public corporation can exercise their right to vote in several ways. First, they can attend meetings to vote directly on company matters, such as the election of the board of directors, who are responsible for overseeing the company's management. Secondly, while reading financial reports does not directly contribute to the voting process, it can inform shareholders' decisions when casting their votes. Lastly, and importantly, shareholders can utilize proxy voting, which allows them to vote without being physically present at the meeting. Proxy voting can be done by mailing a filled-in voting form or, increasingly, through online platforms.
Overall, the correct answer is 'All of the above', as shareholders can attend meetings, be well-informed through financial reports, and utilize proxy voting to exercise their voting rights within a public corporation.
