(D) Self-pollination is the transfer of pollen grains from the anther to the stigma of the same flower or another flower on the same plant.$1$. It is considered a $A$ sure method of pollination because it does not depend on external agents like wind or insects.$2$. It is the $B$ most economic method as plants do not need to produce large amounts of pollen or showy flowers to attract pollinators.$3$.

Continuous self-pollination leads to inbreeding depression and reduces genetic diversity,which is detrimental to the evolutionary process.
