What will be the output range of 'rand.nextInt(100) + 1' in Java?

0 to 100
1 to 100
1 to 101
0 to 99

The correct answer is: 1 to 100

This is because when using rand.nextInt(100), the numbers generated are between 0 (inclusive) to 100 (exclusive), so adding 1 to the result will give a range of 1 to 100. Options A and D are incorrect because the lower bound is not inclusive in rand.nextInt(), therefore the range cannot include 0. Option C is incorrect because adding 1 to the result will give a range of 1 to 101, which is not correct based on the parameters of rand.nextInt(100).
