10. none of these

your answer should be the number (1 - 10) next to the correct value.

Explanation:

Step1: Identify string indices

In Java, substring(startIndex, endIndex) uses 0-based indexing. For s = "Apples and bananas are yummy.", index 0 = 'A', index 1 = 'p', index 2 = 'p', index 3 = 'l'.

Step2: Extract substring

The method returns characters from startIndex (inclusive) to endIndex (exclusive). So s.substring(1, 3) takes characters at index 1 and 2: 'p' and 'p'.

Answer:

1. "pp"
