(D) Toxins (IV) Concanavalin A

Choose the correct answer from the options given below :

  1. A
    A-(II), B-(IV), C-(III), D-(I)
  2. B
    A-(II), B-(I), C-(IV), D-(III)

Correct answer: D

List I contains a list of categories of secondary metabolites or proteins, while List II contains examples of specific compounds.

Terpenoids are a large class of organic chemicals similar to terpenes, and diterpenes are a type of terpenoids. So, A matches with II.

Lectins are a type of protein that can bind specifically to certain sugars and so play a role in recognizing carbohydrates. Concanavalin A is a lectin. So, B matches with IV.

Alkaloids are a class of naturally occurring organic compounds that mostly contain basic nitrogen atoms. Codeine is an alkaloid found in opium poppy. So, C matches with I.

Toxins are poisonous substances produced within living cells or organisms. Ricin is a toxin. So, D matches with III.

Therefore, the correct answer is Option D : A-(II), B-(IV), C-(I), D-(III).
