A Correct answer
Explanation

For first series: 100 x 0.7 x 0.94 = 65.8, so 34.2% discount. For second series: 100 x 0.8 x 0.84 = 67.2, so 32.8% discount. The first series gives a lower final price (65.8 < 67.2), meaning more discount to the purchaser. Successive discounts compound, so order matters.
