B is the best option available:
Multi-party initiatives are becoming increasingly popular among the members of the parliament of Country W. Although legislation proposed under the auspices of more than one party may not adhere as strictly to the agenda of each of the parties involved as legislation proposed by only one party, the political backing of the voting blocs represented by the cooperating parties make such proposals more likely to pass than proposals that come from a single faction alone. The benefit of multi-party initiatives is that legislation important to the general welfare of Country W that might otherwise have foundered in inter-party disagreements can effectively be enacted.
