B. Arthritis II. Autoimmune disorder affecting neuromuscular junction
C. Myasthenia gravis III. Wild contraction in muscle due to low \(Ca ^{++}\)in body fluid
D. Muscular dystrophy IV. Progressive degeneration of skeletal muscle
Choose the correct answer from the options given below :

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

Verified Solution

Answer & Solution

Correct Answer

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

Step-by-step Solution

Detailed explanation

(A) A-III, B-I, C-II, D-IV
Tetany is characterised by rapid spasms or wild contractions in muscles due to low \(Ca ^{++}\) in body fluid. Thus, A matches with III.
Arthritis is the inflammation of joints. Thus, B matches with I.
Myasthenia gravis is an autoimmune disorder affecting the neuromuscular junction leading to fatigue, weakening, and paralysis of skeletal muscle. Thus, C matches with II.
Muscular dystrophy is the progressive degeneration of skeletal muscle mostly due to genetic disorder. Thus, D matches with IV.
The correct matching is A-III, B-I, C-II, D-IV.

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.
