Statement IIA current-carrying wire creates magnetic field around it.

- ABoth true and II explains I
- BBoth true but II does not explain I
- CI true but II false
- DI false but II true
Explanation
Both statements are true: Oersted's experiment shows a compass needle deflects near a current-carrying wire, and the reason is that the current creates a magnetic field around the wire. Statement II directly explains the deflection in statement I. Hence both are true and II is the correct explanation of I.
