The correct option is
D Good healthAfter a careful reading of the poem, we realize that options A to C and E all find a mention in the poem with the exception of option D.
(A) The speaker mentions a calm mind- "Like your own soul, serene, a pattern of your mind."
(B) The speaker also talks about age, growing old and old age-
"Enjoyed his youth, and now enjoys his age"
(C) There is also a mention of friends and friendship- "All who deserve his love, he makes his own"
(E) Wisdom too finds a mention in the poem when the poet calls the country-dweller "wise"- "Just good and wise".
Good health is not mentioned in the poem. The poet does not say anything about the effect of country life on health. There is a mention of age but it has no reference to health. Therefore, D is our answer.
