You have three species A, B, and C. Assume that they form a monophyletic group
A's gene sequence is very similar to B
A has some physical similarities to B.

B's gene sequence is very different from C's
B has some physical similarities to C
SELECT ANY ANSWERS THAT ARE CORRECT
1. A and B are probably closely related
2. B and C are probably closely related
3. A and C are probably closely related
4. B is probably an outgroup while A and C are sister taxa
5. A is probably an outgroup while B and C are sister taxa
6. C is probably an outgroup while A and B are sister taxa

1. A and B are probably closely related - true, as reflected by their close gene sequences which usually represents a very close genetic relationship

2. B and C are probably closely related - false, if their gene sequences are very different then they are probably not so closely related

3. A and C are probably closely related - false, we know A and B are close, and B and C are very different, therefore A is probably also very different

4. B is probably an outgroup while A and C are sister taxa - false, A and B are highly similar

5. A is probably an outgroup while B and C are sister taxa - false, B and C are very different genetically

6. C is probably an outgroup while A and B are sister taxa - true, we know A and B share similar gene sequences, whereas C is distinct.
