The correct answer is B.
Parallel arrays are arrays that have the same number of elements and are indexed in the same way. In this case, the strStates array has 5 elements, and the strCapitals array also has 5 elements. Since Illinois is stored in the second element in the strStates array, its capital (Springfield) is stored in the second element in the strCapitals array, which is strCapitals(2).
Option A is incorrect because Springfield is not the first element in the strCapitals array.
Option C is incorrect because Springfield is not the third element in the strCapitals array.
Option D is incorrect because Springfield is not the zeroth element in the strCapitals array.
