Drop-down 1:
We are told that the day trader made a total profit of $250 from trading 50 shares of a particular company.
Since profit = (selling price – buying price) × number of shares, the stock price must have increased by $250 ÷ 50 = $5 between 9:00 and 13:00.
We need to identify the company whose stock price increased by $5 during that time period. Note that the graph shows stock prices beyond 13:00, but only the price change from 9:00 to 13:00 is relevant to the trader’s profit.
From 9:00 to 13:00, the following price changes occurred. We should check all companies to be certain. No calculator is needed — we can quickly note the differences and identify which company had a price increase of $5.
Company A: 55 → 65, a change of +10
Company B: 20 → 30, a change of +10
Company C: 105 → 110, a change of +5 — Correct
Company D: 65 → 50, a change of –15
Drop-down 2:
At the market close at 16:00, Company C had an overall price change of +$10, from $105 to $115.
I see the 13:00 and 16:00 - is that on purpose to make it trickier? I assume so. Should it say "must have purchased" instead of "most likely"?

Yes, the timings are different to make sure you read the question correctly and not jump to conclusions!
The reason I say 'most likely' is because the value of $250 is approximate. Test takers are expected to eye ball the values so in reality there could be a slight variation in the total profit of $250. However, that variation is small enough that no other option comes close.

We've been told that the day trader makes a profit of $250 after trading 50 stocks of a particular company. This means that the stock he bought had a change of 250/50 = $5 from 9 AM to 13:00. So we are looking for a stock that had gone up by $5 in that time frame. Note that the chart goes beyond 13:00.
In this time from 9 to 13:00 the following price changes occurred. Note that we should check all of them to be safe. You do not need a calculator but can quickly note the differences and which one will be equal to 5.
Company A goes 55 -> 65, i.e. a change of +10 Company B goes 20 -> 30, i.e a change of +10 Company C goes 105 -> 110. i.e. a Change of +5 CORRECT Company D goes 65 -> 50, i.e a change of -15
The Answer is Company C.
In the second part, we've been asked how much the stock has changed by closing time at 16:00. This is a trap in case you look at 13:00 instead of 16:00. Therefore, at 16:00, Stock C is at $115, i.e. the change is 115-105 = +$10.
for the 2nd drop down, when you say approximate price change you mean from 9.00 am - 16.00 pm and not from when the dealer sold the stock that is from 13.00 pm to 16.00 pm? Bunuel - please brief. I picked +5 considering from 13.00 he sold for 110 and at the end it is 115

Yes, the second drop-down refers to the overall price change for that company from market open at 9:00 to market close at 16:00.
