Quizplus · Accepted Answer

At the beginning, the StringBuilder contains "a toyota".

When we call the method sb.insert(2, "landrover"), the StringBuilder becomes "a landrovertoyota".

Then, we call sb.delete(11, 16), which removes the characters "toyot" from the StringBuilder, resulting in "a landrover".

Finally, we call sb.insert(11, " "), which inserts a space at index 11, resulting in "a landrover a".

Therefore, the answer is B, "a landrover a".
