<reasoning>

Identify independent clauses

The sentence consists of two independent clauses:

1. "We won the soccer game"
2. "we lost the football and basketball games"

Analyze punctuation rules for joining independent clauses

• Option 1 uses a semicolon (\(;\)), which is grammatically correct to join two independent clauses.
• Option 2 uses only a comma (\(,\)), which creates an incorrect comma splice.
• Option 3 uses a comma followed by a coordinating conjunction (\(,\text{ but}\)), which is grammatically correct.
• Option 4 separates them into two distinct sentences using a period (\(.\)), which is grammatically correct.

Determine the incorrect option

Option 2 is incorrect because it joins two independent clauses with only a comma, resulting in a comma splice.
