As per my understanding
Conclusion: Handwriting is poor way of predicting personality
P: even though it is used by 3,000 United States firms and by a majority of European companies
P: In a recent study, five graphologists scored no better than chance in predicting the occupations of forty professionals.

I thought option E would serve as an evident inference(correlation between personality and occupation)
Can someone explain how is Option E an assumption?
I am confused here

while its easy to eliminate all options and reach point E . Below point of view might help .
Argument - handwriting aka graphology > poor way to detect personality .(H not connected with P)
evidence - writing did not help predict occupations.
assump - personality can help detect occupation . (P+O .. P is connected with O)

to sum up .. E says personality and occupation are linked hence as per author handrwtin cant detect personality and as personality and occupation are related the graphologists FAILED to detect correct occupation .

(H not connected with P) (P+O .. P is connected with O) so if u can't reach P you can't reach O and this is what conclusion says .
Negation - E - - there is no connection between P and O .. this is supporting opposite of conclusion i.e graphologist scored better because H+P+O all are connected .

Handwriting analysis—also known as graphology—is a poor way to predict personality types, even though it is used by 3,000 United States firms and by a majority of European companies. In a recent study, five graphologists scored no better than chance in predicting the occupations of forty professionals.

Which one of the following is an assumption necessary to the argument?

(A) People in the same occupation usually do not have the same personality type. - WRONG. Even if they had then it makes no sense as to how personality is predicted. All in all this has no impact as such.

(B) Graphology is an effective means of predicting personality types in non-business contexts. - WRONG. Again no impact.

(C) There are more United States firms that do not use graphology than all the United States and European firms that do use it. - WRONG. Out of Scope.

(D) There are several other techniques for predicting personality types that are more accurate than graphology. - WRONG. Again how does that make the conclusion stand more strongly. It might be the case here that others are better but the reasoning offered against the conclusion is not impacted.

(E) There is a correspondence between type of personality and choice of occupation. - CORRECT. If there is none then we are in trouble. Then any analysis is bound to be poor.

Answer E.
