(A) The success of the project depended on the team's

Solution

Commitment fits both blanks: (A) "The success of the project depended on the team's commitment to meet the tight deadlines." Commitment here indicates the dedication required to achieve project goals. (B) "The contract's commitment in ensuring compliance with regulations was critical for the partnership." Commitment in this context refers to the contract's role in adhering to regulatory standards. Efficiency and Flexibility do not fit well in both contexts: Efficiency relates to the ability to achieve results with minimal waste, which doesn’t fit the context of the team’s dedication or the contract’s role. Flexibility involves the ability to adapt to changes, but it doesn’t align with the focus on dedication and adherence in the given sentences.
