The H-zone in the skeletal muscle fibre is due to
(a) the central gap between actin filaments
extending through myosin filaments in the
A-band
(b) extension of myosin filaments in the central
portion of the A-band
(c) the absence of myofibrils in the central portion
of A-band
(d) the central gap between myosin filaments in the
A-band.
