NEET · Biology · STD 11 - 16. Excretory product and their elimination

Match List \(I\) with List \(II\).

List \(I\) List \(II\)

\(A\). Taenia \(I\). Nephridia

\(B\). Paramoecium \(II\). Contractile vacuole

\(C\). Periplaneta \(III\). Flame cells

\(D\). Pheretima \(IV\). Urecose gland

Choose the correct answer from the options given below:

A A-II, B-I, C-IV, D-III
B A-I, B-II, C-III, D-IV
C A-I, B-II, C-IV, D-III
D A-III, B-II, C-IV, D-I

Verified Solution

Answer & Solution

Correct Answer

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

Step-by-step Solution

Detailed explanation

Option (4) is the correct answer because protonephridia or flame cells are the excretory structures in platyhelminthes. Nephridia are the tubular excretory structures of earthworms (Pheretima) and other annelids. Single celled organisms like Paramoecium have contractile vacuoles for excretion. Urecose glands are present in cockroach

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
