To determine which statement is a tautology, we can analyze each option:

1. **A: \( q \lor p \lor \neg q \)**

   - This simplifies as \( q \lor \neg q \) is always true (since a proposition or its negation is a tautology). Therefore, \( q \lor p \lor \neg q \) is also always true, regardless of the truth value of \( p \). Hence, **A is a tautology**.

2. **B: \( q \lor p \to p \land q \)**

   - This can be rephrased as \( (q \lor p) \to (p \land q) \), which is not a tautology. It is false when \( q \lor p \) is true, but \( p \land q \) is false. For example, if \( p \) is true and \( q \) is false, \( q \lor p \) is true, but \( p \land q \) is false. Hence, **B is not a tautology**.

3. **C: \( p \to \neg p \)**

   - This implication is false when \( p \) is true, because \( p \to \neg p \) would imply that if \( p \) is true, then \( p \) is also false, which is a contradiction. Hence, **C is not a tautology**.

4. **D: \( p \land (q \lor r) \)**

   - This is not a tautology because its truth depends on the specific truth values of \( p \), \( q \), and \( r \). For example, if \( p \) is false, the whole expression is false. Hence, **D is not a tautology**.

### Conclusion: 
The correct answer is **A: \( q \lor p \lor \neg q \)**, which is a tautology.
