What C143 test under the Standard ASTM test method?

(b) Test Method for Compressive Strength of Cylindrical Specimen
(c) Test Method for Unit Weight, Yield, and Air Content (Gravimetric) of Concrete

I had been asked this question in final exam.
This interesting question is from Flaws in Concrete and Remedial Measures, Quality of Concrete in chapter Quality Control of Concrete Technology
