Solution

The correct option is A Green chemistry
Green chemistry seeks to develop products and processes that are kind to the environment. This can involve reducing the waste a process creates, using renewable materials, lessening the energy required to form a product, etc.
Both the processes in the question involves forming products which are more friendly towards the environment. Hence, they are the applications of Green chemistry.

Q. A certain drug, manufactured by a Company is tested chemically for its toxic nature. Let the event "THE DRUG IS TOXIC" be denoted by H & the event "THE CHEMICAL TEST REVEALS THAT THE DRUG IS TOXIC" be denoted by S. Let

P (H) = a, P (S / H) = P (¯ ¯¯ ¯ S / H) = 1 - a

. Then show that the probability that the drug is not toxic given that the chemical test reveals that it is toxic, is
