Among the various models of Delta vacuum cleaners, one cannot accurately predict how effectively a particular model cleans simply by determining how powerful its motor is. The efficiency of dust filtration systems varies significantly, even between models of Delta vacuum cleaners equipped with identically powerful motors.
The argument’s conclusion is properly drawn if which one of the following is assumed?
(A) For each Delta vacuum cleaner, the efficiency of its dust filtration system has a significant impact on how effectively it cleans.
(B) One can accurately infer how powerful a Delta vacuum cleaner’s motor is from the efficiency of the vacuum cleaner’s dust filtration system.
(C) All Delta vacuum cleaners that clean equally effectively have identically powerful motors.
(D) For any two Delta vacuum cleaners with equally efficient dust filtration systems, the one with the more powerful motor cleans more effectively.
(E) One cannot accurately assess how effectively any Delta vacuum cleaner cleans without knowing how powerful that vacuum cleaner’s motor is.

We need some relationships between power of motor and other factor (filters) which increases effectiveness of motor and efficiency of other factor (filter).
As mentioned in the option "A"
B - nothing like this mentioned in the argument
C- what about efficiency of filter than so not correct
D- we can't say this without any other supporting premise
E- motor alone is not the factor so wrong

The conclusion of the argument: One cannot accurately predict how effectively a particular model cleans simply by determining how powerful its motor is
The support for this conclusion: The efficiency of dust filtration systems varies significantly even with the same powerful motor
There must be some assumptions made by the author between the effectiveness of a model cleans and the efficiency of dust filtration. A directly states that assumption.
