Meaning: 'Bills' are documents that detail the amount owed for services, in this case, utilities.

Wrong options:

• vouchers: 'Vouchers' are documents that can be used to claim a discount or payment, but they do not fit as they do not represent the charges themselves.
• units: 'Units' refer to individual apartments or spaces, which does not fit as it does not represent what is being paid.
• cells: 'Cells' are typically small rooms or compartments, which is irrelevant in the context of utility payments.
• company: 'Company' refers to a business entity, which does not fit as it does not represent the charges being paid.
• outsource: 'Outsource' is a verb meaning to obtain goods or services from an outside supplier, which does not fit grammatically or contextually.

Correct answer: units

Explanation: The term 'units' refers to individual living spaces within a development. It fits grammatically as it serves as the subject of the clause and contextually explains why agencies pay the utility bills.

Wrong options:

• vouchers: 'Vouchers' do not fit as they refer to documents for discounts, not the entity providing services.
