The following observations are made while testing aggregate for its suitability in pavementconstruction:(i) Mass of oven-dry aggregate in air = 1000g(ii) Mass of saturated surface-dry aggregate in air = 1025g(iii) Mass of saturated surface-dry aggregate under water = 625 gBased on the above observations, the correct statement is

A. bulk specific gravity of aggregate = 2.5 and water absorption = 2.5%
B. bulk specific gravity of aggregate = 2.5 and water absorption = 2.4%
C. apparent specific gravity of aggregate = 2.5 and water absorption = 2.5%
D. apparent specific gravity of aggregate = 2.5 and water absorption = 2.4%
Answer» B. bulk specific gravity of aggregate = 2.5 and water absorption = 2.4%
