To solve the equation \( a^2 - 2a + 1 = 0 \), we can start by factoring the quadratic expression.

Notice that \( a^2 - 2a + 1 \) can be factored as:

\[ (a - 1)^2 = 0 \]

Setting the factor equal to zero gives us:

\[ a - 1 = 0 \]

This simplifies to:

\[ a = 1 \]

Thus, the solution set is:

\[ { 1 } \]

So the correct choice is:

A. The solution set is \({ 1 }\).
