NEET · Biology · STD 11 - 17. Locomotion and movement

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

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

\(A.\) Fibrous joints \(I.\) Adjacent vertebrae, limited movement

\(B.\) Cartilaginous joints \(II.\) Humerus and Pectoral girdle, rotational movement

\(C.\) Hinge joints \(III.\) Skull, don't allow any movement

\(D.\) Ball and socket joints \(IV.\) Knee, help in locomotion

Choose the correct answer from the options given below :

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

Verified Solution

Answer & Solution

Correct Answer

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

Step-by-step Solution

Detailed explanation

The correct answer is option no. (\(3\)) as - Fibrous joints do not allow any movement. This type of joint is shown by the flat skull bones which fuse end-to-end with the help of dense fibrous connective tissues in the form of sutures.

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.
