B is correct. Quarter Fractional experiments can exist for designs with 4 factors, as long as the design is properly constructed.

Option A seems incorrect. A Half Fractional Design for 5 factors would have fewer experimental runs than a Full Factorial Design for 4 factors.

I believe statement D is also incorrect because Half Fractional experiments can exist for designs with 2 factors.

I agree, A doesn't make sense because Half Fractional Designs have fewer runs than Full Factorial Designs.
