Answer: Option (b) is the correct answer.
Explanation:
When an atom is attached to another atom through sharing of electrons then bond formed between the atoms is known as a covalent bond. And, a bond formed by transfer of electrons from one atom to another is known as an ionic bond.
For example, electronic configuration of hydrogen is and electronic configuration of oxygen is
. So, in order to attain stability hydrogen needs 1 more electron and an oxygen atom needs two electrons.
Therefore, two hydrogen atoms need to covalently bond through an oxygen atom leading to the formation of .
Thus, we can conclude that the electronegative oxygen that is central to a water molecule is covalently bound to two hydrogen atoms. These hydrogens are 'bent' to form a angle because four of the outer e- about oxygen are shared with hydrogens.

Explanation:
Hello,
In this case, given the information on the table, we notice that in the first and second run we left the concentration of A constant whereas the concentration of B was doubled from 1.0M to 2.0M, even do, we notice that the concentration of B does not affect the rate as it remains constant in 4M/s.
Nevertheless, by doubling the concentration of A, we double the rate, that is from 1.0 M to 2.0 M, we are able to rise the rate from 4.0 M/s to 8.0 M/s, for that reason the rate law is zeroth-order with respect to B and first-order with respect to A, that in formula is:
Best regards.
