Final answer:
The correct representation of the logical statement given in the question is option a, using logical proposition symbols to denote the conditional and conjunctive relationship between the statements about Sierra, Budweiser, Heineken, and Michelob.
Step-by-step explanation:
The question appears to be about logical statements and their representations using propositional logic symbols. Sierra is hearty only if Budweiser is bland, and it is given that Heineken is balanced and Michelob is complex. We can denote 'Sierra is hearty' as S, 'Budweiser is bland' as B, 'Heineken is balanced' as H, and 'Michelob is complex' as M. The statement 'Sierra is hearty only if Budweiser is bland' can be represented by S implies B or in symbols (S → B). Since 'Heineken is balanced' and 'Michelob is complex' are both given as true, these can be represented as a conjunction: (H ∧ M). In logical notation, 'and' is represented by ∧, and 'implies' is represented by →. Therefore, the correct logical expression that represents the scenario is (S → B) (H ∧ M), which is option a.
