Question

which of the following features is/are characteristic of skeletal muscle? a.) involuntary b.) involuntary and striated c.) voluntary d.) voluntary and non-striated

Explanation:

Skeletal muscle is under voluntary control (we can consciously decide to move it). It is also striated (has a striped appearance under a microscope). Option a) is incorrect as it's not involuntary. Option b) is wrong because it's not involuntary. Option d) is incorrect as it is striated. Only option c) correctly states the voluntary nature (though the full characteristic would include striated too, but among the given options, c is the best as the other options have incorrect parts. Maybe the question is a bit of a simplification).

Answer:

C. Voluntary
