Read the following assertion and reason and select the correct option.
Assertion(A): Copper sulfate should not be used for the control of aquatic weeds, except for algae.
Reason(R): The concentration of copper sulfate required to destroy vegetation will assuredly kill any fish present in the water and probably exceed permissible levels in drinking water.
Both A and R are true and R ts the correct explanation of A.
Both A and R are true and R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Both A and R are true and R ts the correct explanation of A.
Copper Sulfate is the most economical algae control available. Copper sulfate (or Copper Sulphate) is an artificial compound that combines sulfur with copper. The toxicity of it is responsible for killing the bacteria, algae, roots, plants, snails, and fungi, but is toxic to humans. The greatest risk to fish from the use of copper sulfate is killing too much plant material at one time. Decay of plant material creates scarce dissolved oxygen, leading to fish suffocation and death.
