The Correct Option is C

Solution and Explanation

Let \(p\): the match will be played; \(q\): the weather is good and the ground is not wet. The statement is \(p\to q\).
\(\sim(p\to q)\equiv p\wedge\sim q\).
\(\sim q=\sim(\text{good}\wedge\text{not wet})=\text{not good}\vee\text{wet}\).
So the negation is: the match will be played and (the weather is not good or the ground is wet).
Answer: (3) The match will be played and weather is not good or ground is wet.
