Solution

The correct option is A Production of callus
Chromosome counts showed that the callus produced was haploid when the anthers 1) were of a dark-brown to black color, and 2) were cultured in the late tetrad stage of microspore development.. Diploid plants were obtained when the anthers had been cultured in the dark.
So, the correct option is 'A'.
