Assertion:Skeletal muscles contraction is due to shortening of sarcomere Reason:Sarcomere is the functional unit of skeletal muscles

Read the statement regarding myofibril and choose the correct option 1. Each myofibril has alternate dark and light bands. 2. In the centre of each 'A' band is an elastic fibre called 'Z' -line 3. 'A' and 'I' bands are arranged alternately throughout the length of myofibril 4. Sarcomere is the functional unit of contraction 5. Central part of thick filament not overlapped by a thin filament is the 'M' line

Read the given Statements for skeletal muscles (i) Thin filaments are firmly attached to the Z - line . (ii) The light band is also called the I - band and contains mostly actin. (iii) A sarcomere is the functional unit of a myofibril between two adjacent A - bands . (iv) The central part of the thick filament , not overlapped by the thin filament is called the H - zone Which of these is/are CORRECT ?
