The answer to which of the following questions would be the LEAST useful in determining whether the ensuing controversy will be detrimental to Hole-In-One’s profits?
Pre-thinking: Hole-In-One’s profits depend on the impact on revenue due to the effect of the political stand.
A. Whether a significant number of Hole-In-One’s pre-existing customers share the political views held by the boycotters.
If the answer to question in Option A is yes, some of its pre-existing customers might boycott and that could be detrimental to Hole-In-One’s profits. This is useful.
Drop Option A.
B. Whether Hole-In-One’s owners considered the potential financial impacts of taking a controversial political stand before sharing their position online.
Option B is not very useful as only considering potential financial does not help much in determining actual impact on Hole-In-One’s profits. This is not very useful.
Keep Option B.
C. Whether Hole-In-One’s political stand will draw in enough new, like-minded customers to counterbalance any business lost to the boycott.
If the answer to question in Option C is yes, some like-minded customers could counterbalance Hole-In-One’s lost business. This is useful.
Drop Option C.
D. Whether comparable businesses in Sealett that have taken similar political stands have lost revenue as a result of sharing those positions.
If the answer to question in Option D is useful to understand if something similar could happen in the case of Hole-In-One’s. This is useful.
Drop Option D.
E. Whether the controversy over Hole-In-One’s political stand will generate sufficient free publicity to allow Hole-In-One to cut its advertising budget by an amount that would exceed any revenue lost to the boycott.
If the answer to question in Option A is yes, some of its pre-existing customers might boycott and that could be detrimental to Hole-In-One’s profits. This is useful.
Drop Option E.
IMO answer should be Option B.

Answer should be A.
Let's suppose there is no restriction.
In this case :
- - - - -
all 5 places can be fixed by 10 ways (from 1 , 2,3....0).
So total nos of possible no will be 100000.
Now as there is one restriction that 5 is not immediately followed by 9.
So 5 9 - - - in this case balance 3 potion can be fixed by 10 ways , so possible no will 1000.
Similarly, -5 9 - - - will 1000.
- - 5 9 - will 1000.
- - - 5 9 will be 1000.
So, total restricted no will be 4000.
Hence rest will be ans , that is 100000-4000.
Or, 96000.

IMO A is the correct answer.
The number of codes for 5 digits is 10^5 = 100,000
There are 4 position that digit 5 is immediately followed by digit 9. Therefore the number of code for 5 digits that digit 5 is immediately followed by digit 9 = 4*10^3 = 4,000
—> The number of code for 5 digits that digit 5 is NOT immediately followed by digit 9 = 100,000 - 4,000 = 96,000
