The pollution control systems in the factories are not adequate enough for complying with regulations. Domestic companies are not manufacturing such systems. On the basis of this, the author concludes that foreign companies will be the ones having a good amount of buyers for their systems.
It seems fairly logical for the author to come to such a conclusion. But, may be, there is still some information that we dont know of at present, which could shake this conclusion.
I am trying to imagine such a missing information and I could only of this :
What if the regulation also states that before the regulation comes into force, sufficient time will be given for technology knowledge transfer between foreign and domestic companies, or in fact, domestic companies will be given ample time and money in the form of aid to setup production plants for such system. May be then the foreign companies wont be having good amount of buyers.
Looking at options :
1) This option is quite close to what I could think of. It may be a possible correct choice as per me.
2) This option tells us what will foreign companies will do after they have sold their pollution control systems. So this choice has actually already accepted the conclusion. What foreign companies will do later after selling the systems is of no use as a weakener. The systems have sold already, now whats the point of fighting against what has already happened. Incorrect choice.
3) The people are trying best to make the regulation not come into force. But this is not relevant because the author is talking about what might happen if the regulations are implemented. The "if" condition is already taken care of by the author. So it doesn't matter what the people are doing in real and at present, or thinking if the regulation will be implemented or not. We have to focus on what happens if they get implemented. Incorrect choice.
4) Again , like in option 3 , this option is making us divert our attention. It is making us to focus on which country's regulation is stronger. How does that matter ? We have to focus on what might happen after the regulation in Remo gets implemented. Whether it is less strong or more strong compared to that in neighboring nations is not relevant. Therefore, this choice is incorrect.
5) This option tells us what pollution in Remo has done. It only hints and favors the notion that the regulation should come into force. But does it help us in inferring what will happen after it gets implemented ?
Will the foreign companies benefit or not ? We get no idea. Incorrect choice.
Possible correct choice A
