Nephelometry and Turbidimetry Differ Because

Nephelometry and turbidimetry differ because

A) although both measure the effect of aggregates on light passing through a solution, turbidimetry measures the light scattered at 10-90°, and nephelometry measures the light that goes directly through the solution
B) although both measure the effect of aggregates on light passing through a solution, turbidimetry measures the light scattered at 10-90°, and nephelometry measures the light that is polarized
C) nephelometry uses instrumentation but turbidimetry does not
D) although both measure the effect of aggregates on light passing through a solution, nephelometry measures the light scattered at 10-90°, and turbidimetry measures the light that goes directly through the solution
