Years ago, some in the government's intelligence community feared the work of telecommunications researchers at then-emerging private security firms. The government experts concluded that these private firms posed the biggest risk to successful government espionage. As the private security firms began publicly releasing and advertising encryption algorithms and other security products, these government experts saw support for their conclusion when an encryption algorithm that government experts could not break began appearing in countless emails.
Which of the following, if true, most weakens the conclusion of the government experts referred to above?

A) Shortly before the government experts reached their conclusions, two private security companies each claimed to have developed "the world's strongest email encryption algorithm"
B) The private security firms' decision to advertise their products and sell them publicly led to other members of the private sector and academia scrutinizing the encryption algorithms.
C) An open-source encryption algorithm, developed by an academic and freely available from popular websites, is recognized by numerous ex-government code breakers as the most unbreakable algorithm ever developed.
D) An enemy government recently succeeded in placing a spy within the government espionage operations referred to above.
E) To strengthen the reputation of the private security firms, employees of these firms publish information about the strength of their products and the benefits of using them.

Somebody plz explain why B is wrong and howcome C is right?

My thought process:
Conclusion: these government experts saw support for their conclusion when an encryption algorithm that government experts could not break began appearing in countless emails.

(in my mind) the govt experts saw support...that means they are now able to break this encrytion....so to weaken this... option B states.... more the advertisements more other ppl scrutinize the algo. hence, the conclusion (advertisements instead of helping creates more problems) is weakened.

Someone plz explain !!

CONCLUSION:The government experts concluded that these private firms posed the biggest risk to successful government espionage.==>IT MEANS WHATEVER SOFTWARE FIRMS ARE MAKING they are threat to government firms.
they got support to their conclusion by finding a software which government expert were unable to break.

now here government experts are assuming that the software they found is made by THOSE FIRMS.
OK if we can find something which will say that this software is not from THOSE FIRMS then assuption will not hold true...hence it will weaken.


option C:
An open-source encryption algorithm, developed by an academic and freely available from popular websites, is recognized by numerous ex-government code breakers as the most unbreakable algorithm ever developed.
NOW THIS OPTION is creating doubt that this algorithm doesnt belong to those firms...this algorithm is made by some academia.....hence it weakens.

hope it helps

If "the most unbreakable algorithm ever developed" was not developed by private firms, they are not biggest the biggest risk to successful government espionage.
