worked together on rewriting the south african constitution

Explanation:

After Nelson Mandela was released from prison in 1990, he and President F. W. de Klerk collaborated on rewriting the South African constitution. This was a crucial step in the transition from apartheid to a democratic South Africa. The other options are incorrect: they did not struggle for control (they worked together), did not present competing arguments to the UN (they had a joint process), and did not develop a two - state solution (South Africa remained a single state).

Answer:

worked together on rewriting the South African constitution
