The correct options are
A Civil rights movement in USA
B Condition of Prisoners in Guantanamo Bay Prison
C Fight For Water Rights in Bolivia
In the case of Guantanamo Bay and the civil rights movement in the USA, government institutions were not doing enough to protect citizens and prisoners. Institutions are not strong enough to enforce democratic rights. In the case of Bolivia, people's expectations were not respected. Thus, these regions faced the challenge of deepening democracy. The conflict between linguistic groups in Belgium is an example of Challenge of expansion.
