Answer: Option (d) is the correct answer.
Explanation:
A ketone is an organic functional group that contains a carbon and oxygen atom bonded together through a double bond, that is, C=O.
For example, acetone 
is a ketone.
Whereas a hydrocodone is a drug which is used to relieve from moderate to sever pain.It is mostly combined with other drugs and resulting in a chemical formula 
.
A camphor is a volatile white color substance with chemical formula 
. It has aromatic smell and its taste is bitter.
A menthone is also an organic compound with chemical formula 
.
Thus, we can conclude that out of the given options the simplest ketone used as an organic solvent is acetone.
The simple tissues are parenchyma, sclerenchyma and collenchyma. Chlorenchyma is a parenchyma, having chloroplast. It is a simple permanent tissue, having chloroplast.
We can set up an ICE table for the reaction:
HClO H+ ClO-
Initial 0.0375 0 0
Change -x +x +x
Equilibrium 0.0375-x x x
We calculate [H+] from Ka:
Ka = 3.0x10^-8 = [H+][ClO-]/[HClO] = (x)(x)/(0.0375-x)
Approximating that x is negligible compared to 0.0375 simplifies the equation to
3.0x10^-8 = (x)(x)/0.0375
3.0x10^-8 = x2/0.0375
x2 = (3.0x10^-8)(0.0375) = 1.125x10^-9
x = sqrt(1.125x10^-9) = 0.0000335 = 3.35x10^-5 = [H+]
in which 0.0000335 is indeed negligible compared to 0.0375.
We can now calculate pH:
pH = -log [H+] = - log (3.35 x 10^-5) = 4.47
The visual criterion which has to be assessed is to ensure it's not oily or sticky.
<h3>What is Distillation?</h3>
This is a separation technique that involves the use selective boiling and condensation to separate a liquid mixture into different components.
In the case of Crude reaction product , it is best to ensure that it is not oily or sticky before semimicro distillation is done.

The answer to that question would be Activation energy. If would like me to elaborate just let me know. :)
