Suppose an ArrayList list contains {"red", "red", "green"}. What is the list after the following code?

```
String element = "red";
for (int i = 0; i < list.size(); i++)
if (list.get(i).equals(element))
list.remove(element);
```
a. {"red", "red", "green"}
b. {"red", "green"}
c. {"green"}
d. {}

b. {"red", "green"}
