To solve this question, the user needs to understand the concept of substring and character indices.
The given code creates a string object s with value "Bicycle". The variables iBegin and iEnd have been assigned the values 1 and 3, respectively. The substring method is then called on the string object s with two arguments: iBegin and iEnd. The substring method extracts a portion of the string starting at the index specified by iBegin and ending at the index specified by iEnd-1.
Option A is incorrect because the substring method with arguments (1,3) extracts the portion of the string starting at index 1 and ending at index 2. Thus, the output is "Bi".
Option B is correct because the substring method with arguments (1,3) extracts the portion of the string starting at index 1 and ending at index 2. Thus, the output is "ic".
Option C is incorrect because the substring method with arguments (1,3) extracts the portion of the string starting at index 1 and ending at index 2. Thus, the output is "ic", not "icy".
Option D is incorrect because the syntax of the substring method is correct, and there is a matching method signature that takes an int and a char.
Therefore, the answer is:
The Answer is: B. ic
