Option 2 was the best one available at that moment but that option is too forward right now and not the right time to use it either since relationship points with Yura is still low/not high enough (So yeah, none of the 3 options where decent to pick from). Option 1 and 3 are not good either.
Yeah, MC/Ruruna needs better dialog options (Need better INT and WIS stats plus bonus Charm/CHA stat for better dialog options to pick from). Need better seducing skills/stats....Though thankfully she has a the right enough/bare minimum of CHA stats and high LUK stats to bumble her way to success!!!
MC's INT and WIS stat not letting herself know she actually values and has minor feels of affections (Plus lust/h0rny) towards our MC(Real MC) Wakana lol...Too into her 'noble elegant' vampire roleplay Chuuni stuff she been obsessed with since childhood XD
