B

Step-by-step explanation:

The question states that Dimitri payed the same price for all stocks, so they can all be represented as x. The question will be easier to understand if we line up the stock changes in least to greatest order:

- 10.10   - 4.15    - 3.55    + 1.30    + 8.75

    D          A          E            B           C

x is the original price, not one with an increase or decrease, so it is at 0.

- 10.10   - 4.15    - 3.55         x        + 1.30    + 8.75

    D          A          E                           B           C

x is between  - 3.55 and + 1.30, yet 1.30 is closer to 0, so + 1.30 is the closest to x, or the purchase price.

The answer is B, hope this helps :)
