The correct answer is A, $3,150.

First convert the assessed value into $1,000 units:

$840,000 ÷ $1,000 = 840 units.

Next multiply by the stated tax rate:

840 × $15 = $12,600 annual property tax.

Because the question requests the quarterly amount, divide the annual tax by four:

$12,600 ÷ 4 = $3,150.

Therefore, A is correct.

The principal examination issue is recognizing how a tax rate expressed “per $1,000” is applied. Candidates should not multiply $840,000 directly by 15%. The $15 figure is not a percentage; it represents $15 of tax for every $1,000 of taxable assessed value.

Massachusetts municipalities establish property-tax rates based on assessed valuation and applicable classifications. Actual assessments, exemptions, abatements, and municipal rates vary, but examination calculations generally give all information required.
