In the structure of a muscle, several fascicles lie bundled together to form a muscle, just as several (a. bone cells b. ligaments c. osteons) lie together to form compact bone tissue. each muscle fiber, which is a muscle cell, consists of protein fibers. similarly, the matrix that lies outside bone cells consists of a protein fiber called (a. actin b. collagen c. myosin) ?

The answers are c. osteons and B. collagen.

Compact bone tissue is one of the two types of bone tissue. The other one is called spongy bone tissue. Compact bone has a higher density, as the name implies, compared to spongy bone. They are made up of closely packed osteons. 

The matrix that lies outside the bone cells is called connective tissues. Connective tissues are made up of collagen fibers and a combination of other elastin fibers.
