Answer:
The correct answer is - option A. Glass thermometer.
Explanation:
Glass or basal thermometers are the instruments that are use to measure temperature of any surface or organism. These are best choice for the measuring smaller changes in the temperature which can vary up to 1/10th of the degree to 1/100th of the degree.
In this case the temperature variation is 0.05 in the environment of the Toxicodendron diversilobum (poison oak) which can easily be monitor with the help of this glass temperature.
Thus, the correct answer is - option A. Glass thermometer.
