from an external source of power
Explanation:
The energy needed for nuclear fusion comes from an external source of power.
Nuclear fusion is the combination of small sized atomic nuclei to form larger ones.
The reaction releases a huge amount of energy but also requires a large activation energy to start up.
- The energy input require to drive two nuclei into fusion comes from an external source.
- Nuclear fusion has a high activation energy which serves as the energy barrier for this reaction to take place.
- The energy comes from the surrounding and once initiated, spontaneous chain reactions are set up.

Answer:
B carbon
Explanation
Lewis structure or dot structure is an easy way to get the bonding details of atoms in a molecule. If we talk about methane molecule carbon is central atom with four electrons that are bonded to four hydrogen atoms and each bond is single covalent bond.
