Final answer:
The synonym for 'tribute' as a noun is 'Tax'. 'Tribute' often denotes a payment made as a sign of respect, similar to a tax. Correct answer is b) Tax.
Step-by-step explanation:
The word that is a synonym for tribute as a noun is option b) Tax. A tribute historically refers to a payment or gift given as a sign of gratitude or respect, often imposed by a ruler or state, which aligns with the concept of a tax. Options a) Quiver, c) Drip, and d) Scintilla do not have the same meaning as tribute.
A quiver is a case for holding arrows, a drip refers to a small drop of liquid, and scintilla means a tiny trace or spark of a specified quality or feeling, none of which are related to the idea of a tribute. So, the correct answer is b) Tax.
