Answer:
Option A) Demand for CDs has decreased, causing equilibrium price and quantity to decrease.
is the correct answer.
Explanation:
- File-sharing is a common practice nowadays. It helps us by providing access to different files (audio , video, images, documents) to others in a faster way.
- A wide range of files are shared daily by using different means of file-sharing including computer networks and peer-to-peer networking.
- Formerly, the data was shared using CDs but now this system has been replaced with the advent of internet.
- Usage of CDs is dropped drastically and hence their demand is decreased.
- So now the prices of CDs are not in equilibrium and their quantity is also decreased.

Answer:
For question a, it simplifies. If you re-express it in boolean algebra, you get:
(a + b) + (!a + b)
= a + !a + b
= b
So you can simplify that circuit to just:
x = 1 if b = 1
(edit: or rather, x = b)
For question b, let's try it:
(!a!b)(!b + c)
= !a!b + !a!bc
= !a!b(1 + c)
= !a!b
So that one can be simplified to
a = 0 and b = 0
I have no good means of drawing them here, but hopefully the simplification helped!
I believe it is C, I'm so sorry if im incorrect.
