An experiment is carried out to find the concentration of carrot tissue. Four chips are cut from a carrot. At the start, each chip is 40 mm long, 20 mm wide, and 10 mm high. Each chip is put in a different sucrose solution A, B, C, and D. The volumes of the chips are calculated after 2 hours.
| Sucrose solution | Volume of chip (mm3\text{mm}^3mm3) |
|---|---|
| A | 800 |
| B | 8000 |
| C | 80000 |
| D | 80 |
Which sucrose solution has the same concentration as the carrot tissue?
A
B
C
D
