This problem involves identifying which cube among the given options represents a possible rotation of the original cube marked as "O."

Step-by-step analysis:

1. Identifying the key faces on cube O:

   • The visible faces of cube "O" show:
     • A face with three dots connected by curved lines (front face).
     • A face with an "O" (right face).
     • A face with four dots arranged in a "+" pattern (top face).

2. Checking each option (1 through 6):

   • Option 1: The visible faces do not match the arrangement in cube "O" because the face with the "O" is not adjacent to the three dots.
   • Option 2: The visible faces do not match the arrangement in cube "O."
   • Option 3: The visible faces do not match the arrangement in cube "O."
   • Option 4: The visible faces correctly match a possible rotation of cube "O":
     • The face with three dots connected by curved lines is in front.
     • The face with the "O" is on the right.
     • The face with four dots in a "+" pattern is on top.
   • Option 5: The visible faces do not match the arrangement in cube "O."
   • Option 6: The visible faces do not match the arrangement in cube "O."

3. Conclusion: Option 4 is the correct answer as it represents a possible rotation of the original cube.
