The H-zone in the skeletal muscle fibre is due to:

1. The central gap between myosin filaments in the A-band.
2. The central gap between actin filaments extends through myosin filaments in the A-band.
3. Extension of myosin filaments in the central portion of the A-band
4. The absence of myofibrils in the central portion of the A-band.
