Fill in the blanks with suitable words given in the options. The results of the diet will _____ based on numerous _______, including genetic factors, lifestyle habits, and overall health.

"Will" is an auxiliary verb used to indicate future tense. After "will," the verb that follows must be in its base form. The base form 'vary' indicates that the results will change or differ in the future based on various factors. The base form 'arrange' does not fit the context of the sentence. The verbs 'fluctuated' (past tense), 'reflected' (past tense) and 'perfected' (past tense) are not in their base forms. This blank requires a noun to be qualified by the adjective 'numerous'. The noun 'elements' fits the context and indicates that the results of the diet are influenced by a range of contributing factors or conditions. The nouns 'predators' (a person or group that plunders, pillages, or robs, as in war) and 'deposits' (anything given as security or in part payment) do not fit the context. The word 'archaic' (marked by the characteristics of an earlier period; antiquated) is an adjective, not a noun. The word 'accessorise' (to fit or equip with accessories) is a verb, not a noun.
