The answer is a. Going to Viseu first is €57 cheaper than going to Coimbra first.

Lisbon to Coimbra: LC = 70
Lisbon to Viseu: LV = 53
Coimbra to Lisbon: CL = 37
Coimbra to Viseu: CV = 72
Viseu to Lisbon: VL = 52
Viseu to Coimbra: VC = 47

Alternative 1. Lisbon to Coimbra to Viseu to Lisbon:
LC + CV + VL = 70 + 72 + 52 = €194

Alternative 2. Lisbon to Viseu to Coimbra to Lisbon:
LV + VC + CL = 53 + 47 + 37 = €137

Alternative 1 - Alternative 2 = €194 - €137 = 57
Thus, going to Viseu first is €57 cheaper than going to Coimbra first.
