The trap here is that the question asks for a change, not for a big number. Lakeshore has by far the largest cells, around 900, so it grabs the eye, but its count falls every week, so its change is never an increase at all. Big does not mean growing, and a starting value is not a change.
What you actually want is the largest jump from one week to the very next. Go row by row and look at the single biggest step up. Pinecrest's best step is +110, Summit's is +90, and Fairview jumps from 150 to 290 between Week 2 and Week 3, a step of +140. The largest single-week increase is Fairview's +140, so Fairview fills the first menu and 140 fills the second.
The other numbers in the second menu are the slips this question is built to catch. Picking 90 means you found the largest jump but read it off the wrong hub, since +90 is only Summit's best single-week step. Picking 120 means you read a raw cell as if it were a change, since 120 is just Fairview's Week 1 starting count, not a week-to-week increase. Picking 210 means you added several weeks together, since Fairview does grow by 210 over the whole period, from 120 up to 330, climbing 170 of that by Week 3 alone, but those span multiple weeks rather than one week to the next. The question asks for a single week's increase, so the answer is 140, the one clean step from Week 2 to Week 3. Read the question for the word single, then compare consecutive cells in each row. A declining row with huge numbers, a lone starting value, and any multi-week total are all decoys.
