all of the above

Detailed explanation-1: -Answer and Explanation: Carbon is different from most other elements in that it can form single, double, or triple bonds with other atoms (c is correct).
Detailed explanation-2: -Carbon atoms are unique because they can bond together to form very long, durable chains that can have branches or rings of various sizes and often contain thousands of carbon atoms. Silicon and a few other elements can form similar chains; but they are generally shorter, and much less durable.
Detailed explanation-3: -The number of protons and electrons are the same in each isotope but the number of neutrons is not the same and that’s why there is a difference in the atomic mass of these isotopes. Carbon-12 has six neutrons in its nucleus, carbon-13 has seven neutrons and carbon-14 has eight neutrons.
Detailed explanation-4: -carbon group element, any of the six chemical elements that make up Group 14 (IVa) of the periodic table-namely, carbon (C), silicon (Si), germanium (Ge), tin (Sn), lead (Pb), and flerovium (Fl).
