| Column-I | Column-II |
|---|---|
| (a) Motor neuron | (i) Muscle relaxation |
| (b) Acetylcholine | (ii) Signal transmission |
| (c) Troponin | (iii) Calcium binding |
| (d) Myoglobin | (iv) Oxygen storage |
a-ii, b-i, c-iii, d-iv
a-ii, b-iii, c-i, d-iv
a-iii, b-ii, c-iv, d-i
a-iv, b-ii, c-iii, d-i
