Final answer:
The best fit for the given data is the exponential model, with an R2 value of 0.90.
Step-by-step explanation:
The best fit for the given data is the exponential model, corresponding to option B. The value of R2 for the exponential model is 0.90, which indicates a good model fit.
A higher R2 value closer to 1 suggests that the model explains a larger proportion of the variation in the data.
