Concept:Evaluate each argument on whether it directly supports or opposes the statement with valid reasoning.Explanation:Argument I is strong because a uniform tax rate simplifies tax filing and lowers administrative costs.Argument II is weak because a uniform tax rate applies the same percentage to all income levels.Higher-income individuals will pay more in absolute terms, but not a disproportionate share relative to their income.Thus, the argument about disproportionate burden is not logically valid.Answer:Only Argument I is strong.Option A.
