Guys, can you help me to solve this problem?

A cross is carried out between two heterozygous individuals (AaBb) where the genes A and B are not linked genes.
What would be the proportions of genotypic recombinants* amongst the offspring of this cross?

 *A genotypic recombinant is an offspring with a genotype different than both parents for the traits in question.

It is an IB multiple-choice, and my solution does not coincide with any suggested answer (this situation does not happen frequently).

Thank you very much in advance!

Правильный ответ, по замыслу IB - С. Наверное, опечатка. Редко, но бывает.
