The correct answer is D) Daniela is seated to the right of Carlo.
Picture the table from above, everyone facing the middle. "X is to the left of Y" means X sits in Y's left-hand seat.
Alberto is on Beatrice's left.
Alberto isn't on Carlo's right, so Carlo can't be the next seat after Alberto. That puts Carlo opposite Alberto, in Beatrice's right-hand seat.
Daniela gets the last seat, opposite Beatrice.
Going round: Beatrice, Alberto, Daniela, Carlo, each on the left of the one before. So Daniela is on Carlo's right.
The rest don't work: Carlo and Alberto both sit next to Beatrice, not opposite her (A, E), the seat on Beatrice's left is Alberto's (B), and the seat on Carlo's left is Beatrice's (C).
