B. mass
C. length
D. electric current
Length a physical quantity will be measured in meters, therefore option (c) is correct.
A physical quantity can be defined as the characteristic property of a system that is generally quantified in terms of measurement.
Length , a physical quantity -
The physical quantity associated with length can be written as x meter, where x is the numerical value, and the meter specifies the unit .
Meter is represented by m. It is the fundamental unit of length.
Initially, One meter was defined as a quantity that is 1650763.73 times the wavelength of the light emitted in a vacuum .
Length a physical quantity will be measured in meters ,hence option (c) is correct.

Conclusion:
Your conclusion will include a summary of the lab results and an interpretation of the results. Please answer all questions in complete sentences using your own words.
Using two to three sentences, summarize what you investigated and observed in this lab.
Astronomers use a wide variety of technology to explore space and the electromagnetic spectrum; why do you believe it is essential to use many types of equipment when studying space?
If carbon was the most common element found in the moons and planets, what element is missing that would make them similar to Earth? Explain why. (Hint: Think about the carbon cycle.)
We know that the electromagnetic spectrum uses wavelengths and frequencies to determine a lot about outer space. How does it help us find out the make-up of stars?
Why might it be useful to determine the elements that a planet or moon is made up of?
