A	M line
B	A band
C	I band
D	Z line

Explanation:

Detailed explanation-1: -Thick filaments are anchored in the middle of the sarcomere at the M-line. The I-band is the region on either side of a Z-disc that contains only thin filaments and titin.

Detailed explanation-2: -H – zone is the central region of A band with only myosin filaments.

Detailed explanation-3: -The sarcomere consists of a bundle of myosin-containing thick filaments flanked and interdigitated with bundles of actin-containing thin filaments (Fig. 1). The striated appearance of muscle results from the alternation of thick-filament-containing (A-Band) and thin-filament-containing (I-band) regions.
