The correct option is B Loquacious
A loquacious person is one tending to talk a great deal or continuously. For example, "I was talking, as one always does, to a loquacious taxi driver." Hence, Option B is correct. Among the rest of the options, impecunious means having little or no money, voracious means wanting or devouring great quantities of food, avaricious means having or showing an extreme greed for wealth or material gain.These options do not express the intended meaning, hence incorrect.
