The marginal utility from the 4th bottle of soda can be found by looking at the change in total utility from consuming 3 bottles of soda versus 4 bottles of soda. From the table, we see that the total utility from 3 bottles of soda is 26 and the total utility from 4 bottles of soda is 29. Therefore, the marginal utility from the 4th bottle of soda is 29 - 26 = 3. So, the answer is B.
