The answer
4The best rate of climb speed with one engine inoperative
Explanation
Vyse is the best rate of climb speed with one engine inoperative, marked by the blue radial line, and it gives the most altitude gain per unit of time. Vxse is the best angle of climb speed (most altitude per unit of distance). Vmc is the minimum control speed. Vsse is the manufacturer's safe intentional one-engine-inoperative speed, published in the AFM.
Memory tip: Vyse = blue line = 'blue sky' — best rate of climb on one engine.
