C Correct answer
Explanation

Statement 1 is wrong because alachlor is a herbicide used to control the growth of broadleaf weeds and grasses in corn and many other crops. Statement 2 is correct because it mixes well with other herbicides. It is used mainly to control annual grasses and broadleaf weeds in corn (maize), soybeans and peanuts. Statement 3 is correct. Alachlor is slightly toxic because, when it is exposed to levels above the maximum contaminant level (MCL), there occurs slight skin and eye irritation and at lifetime exposure to levels above the MCL, it causes potential damage to liver, kidney, spleen, lining of nose and eyelids.
