Answer: Dell
Explanation: Dell will be selected as per the conjunctive decision rule.
The first standard of Price = 3, is met by HP and Dell as they have prices above the cutoff point, but Samsung will be eliminated from here as it does not clear the cutoff point for price.
The second standard is quality. The cutoff point of 4, for quality, has been met by Dell and Samsung, but the quality of HP is below the cutoff point.
The cutoff point is 4 for ease of use, which has been met by Dell, HP, and Samsung has already been eliminated as per the rule. So Dell will be selected here as per the Conjunctive decision rule.
