A. A bands of muscle fibre are dark and contain myosin.
B. I bands of muscle fibre are light and contain actin.
C. During muscle contraction, the A bands contract.
D. The part between two Z lines is called sarcomere.
E. The central part of the thin filament not overlapped by the thick filament is the H zone.
- a)A, C and E are correct, while B and D are incorrect.
- b)A, B and D are correct, while C and E are incorrect.
- c)A, B and C are correct, while D and E are incorrect.
- d)A and B are correct, while C, D and E are incorrect.

Read the statements carefully and comment on them.A. A bands of muscle...
The correct answer is option 'B': A, B and D are correct, while C and E are incorrect. Let's analyze each statement to understand why this is the correct answer.
A. A bands of muscle fibre are dark and contain myosin:
- This statement is correct. A bands are the dark bands observed in muscle fibers and they contain myosin, a protein responsible for muscle contraction.
B. I bands of muscle fibre are light and contain actin:
- This statement is correct. I bands are the light bands observed in muscle fibers and they contain actin, a protein that interacts with myosin during muscle contraction.
C. During muscle contraction, the A bands contract:
- This statement is incorrect. During muscle contraction, the A bands do not contract. Instead, the I bands contract as the actin filaments slide over the myosin filaments, causing the sarcomere to shorten.
D. The part between two Z lines is called sarcomere:
- This statement is correct. The sarcomere is the basic unit of muscle contraction and is defined as the region between two Z lines. It consists of overlapping actin and myosin filaments.
E. The central part of the thin filament not overlapped by the thick filament is the H zone:
- This statement is incorrect. The H zone is the central part of the sarcomere where only thick filaments (myosin) are present, and there is no overlap with thin filaments (actin).
Therefore, option 'B' is the correct answer as it correctly identifies which statements are correct and incorrect.

(C)In muscle contraction length of A band doesn't change
(E)The Central part of the "thick" filaments not overlapped by "thin" filament is H-zone .
So C and E are incorrect
(E)The Central part of the "thick" filaments not overlapped by "thin" filament is H-zone .
So C and E are incorrect
