The pH scale goes from 0 to 14, with 7 being neutral (pure water). Anything below 7 is considered acidic and anything above 7 is considered basic. Based on the information given, the food has a pH between pure water (neutral) and an oven cleaning solution (very basic). Lemon juice and black coffee are acidic and have a lower pH than pure water, so they are not the correct answer. Red wine is acidic and may have a pH around 3-4, which is lower than pure water but still higher than an oven cleaning solution, so it is also not the correct answer. Egg white is slightly basic with a pH around 7.6-8, which is within the range of being higher than pure water but lower than an oven cleaning solution. Therefore, the answer is C) egg white.
