1. A would be true EXCEPT for the except part. As far as I know, absorbance values have significant figures also.
B. I don't know that ALL numbers should be recorded.
C is true.
D is true.
E can't right if C and D the only true ones.

2. Absorbance doesn't have units, and you should record all the numbers in a digital readout, so all of them are true.
