The correct answer is C. irrigation. Irrigation is the technology or practice of diverting water from a river or another source and channeling it towards farmlands. This enables farmers to supply water to their crops for irrigation purposes. To arrive at this answer, one can use a variety of methods. One way is to use prior knowledge or personal experience. Another way is to eliminate the incorrect options. We can rule out "foraging" (which refers to searching for food) and "domestication" (which refers to the process of taming and breeding animals for human use) as they are not specifically related to leading water to farmlands. "Selective breeding" is also not correct as it refers to the process of breeding specific plants or animals to obtain desired traits. This leaves us with the only remaining option, which is "irrigation."
