This is an analogy question where we must identify the relationship between the first pair of words and apply it to the second pair.
A "sail" is something that is operated or used by a "sailor." The relationship is that the second word is the person who uses or operates the first word.
Similarly, a "pick" is something that is used or operated by a "picker." This could refer to a tool used by someone to pick fruits, vegetables, or other items.
Option (A), "Choose," is an action, not a person, so it does not fit the analogy pattern.
Option (B), "Tool," is a category of object but does not match the person-using-object relationship.
Option (C), "Nose," has no direct logical connection to "pick" in this analogy context.
Thus, the correct match is option (D) "Picker."
