All of the following relationships are correlated. Which relationship most likely reflect both correlation and causation?

a. The lawn growing faster is associated with picking more weeds
b. The lawn growing faster is associated with the more that it rains
c. The lawn growing faster is associated with trimming the bushes more
d. The lawn growing faster is associated with having more guests over to your house

c. The lawn growing faster is associated with trimming the bushes more

In this scenario, it is likely that trimming the bushes more is causing the lawn to grow faster, as the act of trimming bushes can provide nutrients to the soil and promote overall lawn health and growth. The other relationships are more likely to be correlated but not necessarily directly causing the lawn to grow faster.
