Verified by Experts

The correct Answer is:
d
I-band is considered as a light band and contains a protein actin. It has a dark membrane called Z-line (not M -line) which is an elastic fibre.
It is also Z-disc or Doble's line. The part of the myofibril between two successive Z-lines is called sacromere (functional unit of contraction).
