Read the\u00A0supporting details\u00A0then answer the following question. According to the passage, which of the following options should be done before planting a tree?

This answer is found in the first sentence of the second paragraph. The passage does not state anything about trimming the tree\u2019s dead branches; therefore, that option can be quickly eliminated. However, the passage does mention the need to lightly mulch around the tree and the need to water the tree, but those two items are done after the tree is planted, not before.
