Concept:
Vocabulary questions involving synonyms require us to identify words that have meanings similar or nearly identical to the given word. The word Obfuscate means to make something unclear, confusing, difficult to understand, or deliberately obscure.
To determine the correct answer, we must examine the meaning of each word individually.
Step 1: Analyze word (a) -- Illuminate.
The word Illuminate means:
• To shed light on
• To clarify
• To make something easier to understand
Example:
“The teacher's explanation illuminated the difficult concept.”
Since illuminate means to make something clear, it is opposite in meaning to obfuscate.
Therefore, (a) is incorrect.
Step 2: Analyze word (b) -- Confound.
The word Confound means:
• To confuse
• To bewilder
• To make difficult to understand
Example:
“The complicated instructions confounded the participants.”
This meaning closely matches the meaning of obfuscate.
Therefore, (b) is correct.
Step 3: Analyze word (c) -- Explicate.
The word Explicate means:
• To explain
• To interpret
• To clarify in detail
Example:
“The professor explicated the theory thoroughly.”
Since explicate means to make something clear, it is opposite in meaning to obfuscate.
Therefore, (c) is incorrect.
Step 4: Analyze word (d) -- Muddle.
The word Muddle means:
• To confuse
• To mix up
• To make unclear
Example:
“The contradictory statements muddled the issue.”
This meaning is very close to the meaning of obfuscate.
Therefore, (d) is correct.
Step 5: Determine the correct combination.
We found that:
\[
(b)\ \text{Confound}
\]
and
\[
(d)\ \text{Muddle}
\]
are the words that closely match the meaning of obfuscate.
Therefore,
\[
(b) \text{ and } (d)
\]
form the correct combination.
Hence, the correct answer is Option (C).
