Final answer:
Christine owns 40% of the stock in the online corporation, which is equal to 800 shares.
Step-by-step explanation:
To find out how many shares Christine owns, we can first calculate what 1% of the total shares would be. This can be done by dividing the total number of shares by 100. So, 2,000 shares divided by 100 equals 20 shares. Since Christine owns 40% of the stock, we can multiply the 1% value by 40 to find out how many shares she owns, which is 20 * 40 = 800 shares. Therefore, the correct answer is option C) 800.
