pls pls need ur help?

A rod of Pyrex glass is precisely measured against an aluminum measuring stick at a temperature of 20°C, and the length of the rod is measured as exactly 25.0 cm. The temperature in the lab is then raised to 35°C for one hour, and then the Pyrex rod is measured a second time against the same measuring stick. The second measurement of the rod’s length can be expected to be:
A. 25.0 cm.
B. greater than 25.0 cm.
C. less than 25.0 cm.
D. less than or equal to 25.0 cm.

The coefficient of linear expansion for aluminum is much greater than that for Pyrex, so the aluminum measuring stick will increase in length more than the Pyrex rod when the temperature increases. Therefore, the measurement will show that the Pyrex rod is less than 25.0 cm even though both the rod and the measuring stick increased in length.
