Regarding Assertion [A] and Reason [R], choose the correct option.
Assertion [A] : Muscles can only pull on structures not push.
Reason [R] : Skeletal muscles are often arranged in pairs that pull bones in opposite directions.
Assertion [A] is True and Reason [R] is True and is a correct explanation to [A].
Skeletal muscles move bones by pulling on them. Because we control this movement, they are called voluntary muscles. Muscles can pull but not push, so skeletal muscles are often arranged in pairs that pull bones in opposite directions.
