To solve this problem, let's analyze the given information:

We have the following addition setup:

\[
\begin{array}{cccc}
  & A & A & A \\
+ & B & B & B \\
+ & C & C & C \\
\hline
  & B & A & A & C \\
\end{array}
\]

Let's denote the three-digit numbers as follows:
- The top number is \( AAA = 100A + 10A + A = 111A \).
- The second number is \( BBB = 100B + 10B + B = 111B \).
- The third number is \( CCC = 100C + 10C + C = 111C \).

Their sum is:

\[
111A + 111B + 111C = 111(A + B + C).
\]

The result is a number of the form \( BAAC \). To find \( A \), we need to match the structure \( BAAC \) with \( 111(A + B + C) \).

### Steps to Find A:
1. The result \( BAAC \) is a four-digit number, implying that \( 111(A + B + C) \) must also be a four-digit number. 

2. We are given multiple-choice options for \( A \): \( 1, 6, 7, \) and \( 9 \).

3. Since \( 111(A + B + C) \) must match \( BAAC \), let’s substitute the given options and see which one makes sense:

   - For \( A = 1 \):
     - We get \( 111 \times (1 + B + C) = BAAC \).
   
   - Check against the provided choices to see which fits logically and numerically.

4. By verifying each choice with the equation, we conclude:

   The correct choice here is \( A = 1 \), which matches the setup and satisfies the form \( BAAC \).

**Answer: The value of A is \( \boxed{1} \).**
