A)Enhanced water table regulation✓
B)Selective breeding of maize
C)Rotation using native legumes

Chinampas regulate temperature gradients because the raised beds are surrounded by water, providing thermal mass via evaporative cooling and heat retention; therefore, it avoids temperature shock, rather than depending on solely genetic adaption or external topography changes.
