I agree -- with your answer and with the too-easy part!!

Thank-you. I guess I shouldn't complain but I want to challenge myself

Good job! You got the correct answer. It's not necessary for every question to be difficult. Sometimes, they can be straightforward and simple. In this case, the word "equal" refers to having the same quantity or value. Since Sam had to mix equal parts of the two chemicals, option C is the correct choice. Remember, when selecting an answer, it's important to carefully read and understand the question, as well as all the available options, to ensure you make the right choice.
