C.

D.
Cladding

Explanation:
A BNC refers to a Bayonet Neil Concelman RG58 connector for
10Base2. Fiber optic cable has three basic physical elements, the core,
the cladding, and the jacket. The core is the innermost transmission
medium, which can be glass or plastic. The next outer layer, the
cladding is also made of glass or plastic, but has different properties,
and helps to reflect the light back into the core. The outermost layer,
the jacket, provides protection from heat, moisture, and other environmental
elements. Source: Gigabit Ethernet by Jayant Kadambi, Ian
