Which of the following best describes the relationship between President George H. W. Bush and Soviet leader Mikhail Gorbachev?

Bush and Gorbachev met several times and negotiated important arms-control agreements as the Cold War eased. For example, they signed the START treaty in 1991, which reduced the number of strategic nuclear weapons. Their relationship was cooperative rather than hostile, so “They negotiated arms-reduction agreements” is the best description.
