I'd go with B and D. Moving from problem to solution space is crucial in this phase, and evaluating feasibility, viability, and desirability is a must.
Definitely B and C - those capture the essence of the validation phase. Checking feasibility, viability, and desirability, and then iterating based on feedback is key.
