o+
ab+
b+

Explanation:

1. Analyze A and B agglutination: Agglutination in both A and B wells means the blood has both A and B antigens, so it's AB type.
2. Analyze Rh agglutination: No agglutination in Rh well means Rh - (negative), as agglutination would indicate Rh+.
3. Combine results: AB type with Rh - gives blood type AB-.

Answer:

AB- (from the options: AB- )
