Answer 1

The Correct Option is B

Let's analyze the sentence:
Step 1: Understand the meaning of the sentence:

• The sentence talks about water being affected negatively by chemicals and waste from industries.

Step 2: Meaning of the options:

• Refined: improved by removing impurities — opposite of what happens here.
• Polluted: contaminated or made dirty — fits correctly.
• Filtered: passed through a filter to remove impurities — opposite context.
• Purified: made pure — opposite context.

Therefore, the most appropriate word is polluted.
