Answer:

Option C) 0.57

Step-by-step explanation:

We are given the following in the question:

Average, $\mu_0$ = 260 calories

Standard deviation, $\sigma$ = 35 calories

$\mu_1$ = 240 calories.

We have to find the Cohen's d effective size.

Formula:

$d = \bigg|\dfrac{\mu_1 - \mu_0}{\sigma}\bigg|\\\\d = \bigg|\dfrac{240-260}{35}\bigg|\\\\d = 0.57$

Thus, the Cohen's d effective size is 0.57

Thus, the answer is

Option C) 0.57
