Which best explains US concerns regarding Chile during Nixon’s first term?

During Nixon’s first term, Chile elected Salvador Allende, a Marxist, as president in 1970. The Nixon administration feared that Chile could become a model for communist influence in Latin America and supported efforts to undermine Allende’s government. This matches the choice about pressuring Chile’s Marxists over fears of a Communist revolution; the arms talks and space race were not the central concern.
