Lower the self inductance of a coil less the delay in establishing steady current through it because lower will be the inductive reactance which will offer less opposition to the flow of current.
Hence, assertion is false.
Hence, assertion is false.

Assertion (A) Explained
The assertion states that "Lower the self inductance of a coil, more the delay in establishing steady current through it." This is incorrect.
- Self-inductance is a property of a coil that quantifies its ability to oppose changes in current.
- A coil with lower self-inductance will establish steady current more quickly, not more slowly.
Reason (R) Explained
The reason states that "An inductor opposes a sudden change in current." This statement is true.
- Inductors resist rapid changes in current due to the electromagnetic force they generate.
- The greater the self-inductance, the more it opposes changes in current, leading to a longer time to reach steady state.
Conclusion
Given the above explanations:
- Assertion (A) is false because lower self-inductance does not cause more delay.
- Reason (R) is true as it accurately describes the behavior of inductors.
Thus, the correct answer is option 'D': A is false, but R is true.
