B) ​He took systematic notes and was able to identify patterns of heredity.
C) ​He bred garden plants to obtain higher yields.
D) ​He worked to breed garden plants to obtain better varieties.

Mendel's approach to gardening was scientific because he took systematic and quantitative notes and observed patterns of heredity. He then used these observations to formulate his laws of inheritance, which served as the foundation for the modern study of genetics. He was not necessarily focused on creating commercial plants or obtaining better yields, but his methodical and empirical approach to studying heredity is what makes his work scientific.
