Secret garden

which of dickon's traits does his drawing of the missel thrush best symbolize?

a.
his talent as an artist

b.
his trustworthiness

c.
his honesty

d.
his skill with plants and animals

Since this drawing is his way of reminding her that she and their garden are "as safe as a missel thrush", it makes her one of the many creatures whose secrets he keeps faithfully. So, having that in mind, I would say the correct answer is A) his trustworthiness. 

C, hope this helps. The reason it’s C is because all the other answer wouldn’t make sense.
