Followings are the statements related to soil colloids.
(A). Soil colloids are inorganic in nature.
(B). Soil colloids are of extremely small size, so that they can not be seen with an ordinary light microscope.
(C). Soil colloids exhibit a large specific surface area.
(D). Soil colloids are always positively charged.
Choose the correct answer from the options given below:

Show Hint
To solve complex true/false combinations in competitive exams, use the elimination method:
Since soil colloids are predominantly negatively charged (ruling out statement D), any option containing (D) can be safely crossed out, leaving the correct option instantly.
