The equation is simple
M1V1 = M2V2
The one trick is to realize that H2SO4 has 2 molesof H+ ions for every mole of acid. So that the molarity of H+ ions is twice the amount yuu have for the H2SO4.
Now just plug in and solve for the mL of acid

35 mL x 0.737 M = 25.795 millimoles of H2SO4
you need twice that amount of KOH
51.59 millimoles = X mL x 0.827
X m= 62.38 mL of KOH
answer is d. 62.4 mL
NOTE: Molarity = moles/liters
rearranging gives moles = Molarity x liters
