PLEASE Include Explanation

Read the scenario and pick the most appropriate nonparametric statistical test (assume several assumptions of parametric tests were violated).
Imagine that marketing researchers working for a food company want to determine whether children would prefer ketchup of a different color. They develop green and blue to compare to their standard red (all taste the same). They have children taste all three colors of ketchups (a correlated-groups design) and rank each on a scale of 1 – 10.
