Question

Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): Hot dilute soup is also called primitive broth.
Reason (R): It contains complex micromolecules like enzymes and DNA.
In light of the above statements, choose the correct answer from the options given below.

• A. Both (A) and (R) are true and (R) is the correct explanation of (A).
• B. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
• C. (A) is true but (R) is false.
• D. (A) is false but (R) is true.

Hint:

The hot dilute soup contained simple organic molecules, not complex macromolecules like enzymes and DNA.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept
According to the theory of chemical evolution, simple organic compounds formed in the early ocean from the primitive atmosphere.

Step 2: Check the Assertion
Haldane called this hot dilute soup the primitive or prebiotic broth, so the Assertion is true.

Step 3: Check the Reason
The broth contained simple organic molecules such as sugars, amino acids, fatty acids and nitrogen bases. Enzymes and DNA are complex macromolecules that arose much later, so the Reason is false.

Final Answer:
The Assertion is true but the Reason is false. \[ \boxed{\text{(C) }\text{(A) is true but (R) is false.}} \]
