Explanation:

- Given statements:

- B = D and C = U

- B > G

- U > R

- C > S

- Option Assessments:

1. S < C

- This is true because C > S.

2. S < U

- True as U is same as C (C = U), and C > S.

3. C < R

- This is incorrect since U > R and C is equal to U. Hence, C > R.

4. G < D

- True because B = D and B > G, hence D > G.

- Correct Option:
