Assume that we have a Random object referenced by a variable called generator. Which of the following lines will generate a random number in the range 5-20 and store it in the int variable randNum?

a)```
randNum = generator.nextInt(15) + 5;
```
b)```
randNum = generator.nextInt(15) + 6;
```
c)```
randNum = generator.nextInt(16) + 5;
```
d)```
randNum = generator.nextInt(16) + 6;
```
e) none of the above

c)```
randNum = generator.nextInt(16) + 5;
```
