Which one of the following interspecific crosses will be choosen to artificially resynthesise the Gobhisarson (Brassica napus) oil-yielding crop?

Brassica campestris × Brassica oleracea is one of the following interspecific crosses that will be chosen to artificially resynthesize the Gobhi sarson (Brassica napus) oil-yielding crop.
Interspecific hybridization is the crossing of two species from the same genus. This allows the exploitation of useful genes from wild, unimproved species for the benefit of the cultivated species.
Brassica is a genus of plants in the cabbage and mustard family (Brassicaceae). The members of the genus are informally known as cruciferous vegetables, cabbages, or mustard plants.
