**Concept: The question tests on the application of Algebra in a DS format**

**Solution:**

**Statement 1**: 5p - 20 = 5

From this we can get the value of p, which is 5.

Answer options could be A or D. Therefore Statement 1 Alone is **Sufficient****Statement 2:** (p - 10)^2 = p^2

Expanding p^2 - 20p + 100 = p^2

Again we can get a value for p from this equation which is 5.

Therefore Statement 2 Alone is **Sufficient.****Option D**
