Which one of the following pairs is correctly matched?

In Fritillaria type, out of four nuclei formed, one nucleus remain towards the micropyle, and the rest three at the chalazal end. The chalalazal nuclei fused together to form 3n nucleus. Both the cells then undergo mitotic division and again form a tetrasporic stage. Out of four nuclei, two remain at each pole. All the nuclei then undergo mitotic division and form eight nuclei. Thus it is called tetrasporic 8- nucleate type.
