What impressionist techniques did monet use in waterlily pond, harmony in pink?

a. chiaroscuro and outlines defined shapes
b. orthogonal lines and one-point perspectives
c. muted shadows and a neutral color palette
d. lively brushstrokes and dabs of pure color

i had to look at it a few on b and c because i thought it could be c but  got to looking more and its b, because yes it uses some neutral colors in it but green is not a neutral color it is a secondary color and its using both secondary and neutral colors and the answers d and a to me anyway seemed like to simple and their trying to throw u off because yes their are lively brushstrokes and daps but thats a throw off answer and a, there are not defined shapes in there but the bridge if u want to count that as a shape and the trees arent a shape so that would only leave u with answer b
