P1: Many factories install sophisticated filtration systems to reduce air pollution.
p2: Factories using a new biofiltration technology have lower pollution levels, even when their overall production rates increase.
P3: This suggests that biofiltration technology provides pollution control that is more effective than that of traditional filtration systems.
We need to infer
(A) All factories will eventually adopt biofiltration technology to comply with future environmental regulations. (Can't make predictions)Eliminate
(B) Traditional filtration systems may not maintain effectiveness at higher production rates as effectively as biofiltration technology. (Yes, as in the passage mentioned, as pollution is expected to increase with the production , but it hasn't increase from the industries that are using biofiltration) Answer
(C) Biofiltration technology is less costly to maintain than traditional filtration systems. (Can't say anything about cost)Eliminate
(D) Factories not using biofiltration technology are the largest contributors to air pollution. (Largest???? how can we say that, probably they are not polluting industry at all)Eliminate
(E) Increased production rates always lead to higher pollution levels. (Can't say this, as they can use the biofiltration thing, so they won't lead to much pollution) Eliminate

B is the correct answer because it shows the reason why the author thinks that BFT is more effective than traditional filtration system. Other option are out of scope/cannot be inferred with 100% surety

A : This is not mentioned in the statement as it only talks about effectiveness, not regulations or future trends
B : This is correct because the analyst says biofiltration works better even when production increases meaning traditional systems may not handle increased production as well
C : There is no mention of cost at all
D : There is no comparision between factories or how much pollution they emit
E : The statement says biofiltration reduces pollution even with increased production, so this option is incorrect.
