In this antonyms question, choose the word which is opposite in meaning to the given word "Rebate", which usually refers to a partial refund or discount.

Introduction / Context:
This vocabulary question asks you to find the antonym (opposite in meaning) of the word "Rebate". The word "rebate" is commonly used in commerce and taxation to refer to a partial refund, discount or reduction in the amount to be paid. Antonym questions test whether you can not only recognise the meaning of a word but also identify a term that expresses the reverse concept.

Given Data / Assumptions:

• The target word is "Rebate".
• Options are: "Deduction", "Bonus", "Increase", and "Remission".
• "Rebate" means a partial return of money or a reduction in price or tax.
• The correct antonym must express the idea of raising an amount or making it higher instead of lowering it.

Concept / Approach:
To find an antonym, first clarify the core idea of the original word. A rebate reduces what you have to pay or gives some money back. Opposites of reduction include "increase", "surcharge" or "mark up", any term that involves an upward change. Among the options, "Increase" is the one that directly means making something larger or higher. The other options, "Deduction" and "Remission", are similar to "rebate" rather than opposite, and "Bonus" has a different sense, though still involving extra money.

Step-by-Step Solution:
Step 1: Recall that "rebate" means a partial refund or discount (a downward adjustment in amount).Step 2: Look for a word that signals an upward adjustment or rise in amount.Step 3: Check each option: "Deduction" means a subtraction; "Bonus" is an extra payment; "Increase" means a rise; "Remission" means cancellation or reduction of a payment or penalty.Step 4: Recognise that both "Deduction" and "Remission" are close in meaning to "rebate" because they also involve reduction.Step 5: Conclude that only "Increase" expresses the opposite idea of raising or enlarging an amount and is therefore the antonym.

Verification / Alternative check:
Test the words in simple financial sentences. "The government announced a tax rebate" means taxes are partly returned or reduced. The opposite situation would be "The government announced a tax increase", where taxes go up. A "tax deduction" or "remission of penalty" are like rebates, not their opposites. A "bonus" is extra money given, but it is not the opposite of a discount; rather, it is a reward or additional payment. This comparison confirms that "Increase" is the clearest antonym in the list.

Why Other Options Are Wrong:
"Deduction" means subtracting an amount from a total, for example in "tax deduction". This is close to "rebate", not opposite. "Bonus" means an extra payment given as a reward or incentive; it does not reverse a rebate, and it does not directly reflect price or tax going up. "Remission" means cancellation or reduction of a debt, charge or penalty, again similar in effect to a rebate. None of these options describe raising an amount, which is the opposite of reducing it.

Common Pitfalls:
Students often confuse synonyms and antonyms, especially when several options feel financially positive or negative. Seeing words like "deduction" and "remission", some candidates might think they are complex and therefore correct, without noticing that they share the same direction of meaning as "rebate". To avoid this, always ask yourself: does this option describe more money or less money, higher amount or lower amount, compared to the original word? For "rebate", the opposite must involve an increase, not another kind of reduction.

Final Answer:
The correct antonym is Increase, because "rebate" refers to reducing or refunding part of a payment, while an "increase" refers to raising the amount to be paid.
