Answer:
b. exit barriers are high
Explanation:
Declining industries are those industries wherein the industry has saturated and experiences a negative growth. The characteristic of such industries being the products are lesser in demand.
For instance, cassettes and magnetic tapes industry was in demand until the arrival of more advanced forms such as compact discs and usbs, post which those industries turned into declining industries. 
A declining industry with high barriers to exit would experience a greater competition since the barriers would encourage competition instead of withdrawal. And with higher costs of withdrawal, the firms continue producing at negative growth. 
 
        
             
        
        
        
As far as I remember the four stages or steps in production planning and control are:   
- Routing,
- Scheduling,

- Follow-up.
to me, it seems to be part of the <u>scheduling </u>step. 
Good luck on your exam
 
        
             
        
        
        
Plate counting method is reported in terms of colony forming units (cfus). Colony-forming unit (CFU, cfu, or CFU) is a unit used in microbiology to measure the number of viable microorganisms (bacteria, fungi, viruses, etc.) in a sample that can reproduce through binary fission under controlled conditions. 
In contrast to microscopic analysis, which counts all cells, living or dead, counting with colony-forming units requires cultivating the bacteria. When counting colonies, it is unclear if the colony originated from one cell or a collection of cells because visual appearance of a colony in a cell culture to requires the significant growth.

Answer: B) The option premium is greater or equal to its intrinsic value because of the time premium.
Explanation:
The option premium can be calculated by adding the time premium and the intrinsic value. The time premium is the part of the option premium that accounts for the time remaining till the premium matures while the intrinsic value is the difference between the value of underlying asset and the strike price.
As the time premium can be zero but never negative, the option premium can either be greater than its intrinsic value or equal to it. It cannot be lower than it because of the time premium.
