Answer: A
Explanation:
As per Bohr model, the shells from innermost to outermost are filled in the order: 2, 8, 8, and so on (that's a bit more advanced level). The inner shells, which are closest to the nucleus, are filled first.
Hence, the inner shell has space for two electrons only. It cannot occupy 3 or 4 electrons.
Innermost shell = 2 electrons
Now, carbon has six electrons in total. So, 6-2 = 4 electrons are left.
The rest four electrons will go in the 2nd shell which can occupy maximum 8 electrons.
So, 2nd shell = 4 electrons
=> Electronic configuration of Carbon: 2, 4
an organic compound consisting mostly of chains of carbon compounds.
Answer:
I believe D but that's wrong it's definitely C

Ask farmers in the location to help in mining bauxite
This will give the farmers a source of income; whereas, the other options do not give benefit to either the mining company of the farmers. Only one side profits in the remaining situation.
Adaptive immunity.
When antibodies are produced by lymphocytes, the body is conducting adaptive immunity.
Adaptive immunity is the body's way of identifying the presence of an antigen, recognizing what type of antigen it is, and producing antibodies that are specifically designed to attacked the said antigen.
