Question

which plant is being measured correctly?
plant a
plant b
plant c

Explanation:

To determine the correctly measured plant, we analyze each:

• Plant A: The ruler is not aligned with the base of the plant (soil level), so measurement is incorrect.
• Plant B: The ruler at the base is properly aligned with the soil (the small ruler shows the base measurement, and the tall ruler can be used to measure height from the base), and the measurement setup is correct.
• Plant C: The plant is bent, and the ruler is not aligned with the base (or the measurement point is on a bent part, not the actual height from the base), so incorrect.

Answer:

Plant B
