    Explanation:

    - First, calculate the number of females and males in Company A:

    - Females = 30% of 1200 = 0.3 * 1200 = 360.

    - Males = 1200 - 360 = 840.

    - Determine the number of officers among males in Company A:

    - 4/7 of males are officers = (4/7) * 840 = 480.

    - Determine the number of non-officers among females in Company A:

    - 1/6 of females are non-officers = (1/6) * 360 = 60.

    - Therefore, female officers = 360 - 60 = 300.

    - Calculate total number of officers in Company A:

    - Male officers + Female officers = 480 + 300 = 780.

    - The correct option is Option 3: 780.
