The correct answer is C.
These types of questions can be solved in several different ways. One way is to extract as much information as we can from the question, and then see which answer choice adheres to what we know. For instance in this case, the first thing we can deduce is the working days of Thomas and Sam. Since Thomas works on Mondays, according to the first condition, we conclude the following:

Mon
|
Tue

Wed

|
Fri
|

We know that Winona does not work on Mondays and Fridays. We also know that Victor does not work on the same days as Thomas, who does work on Mondays and Fridays. Since both Winona and Victor do not work on Mondays and Fridays, we deduce that Uma does. The only answer choices that fit this conclusion are C and D. Add that to the fact that Victor cannot work on Wednesdays, either, and you are left with answer choice C as the only possible answer.
Another way to approach this question is to check each of the answer choices, and eliminate the ones which violate the above conditions.
(A) The setup the answer dictates is:
| |
Mon
|
Tue

Thu

According to the fourth condition, Thomas and Victor cannot work together. Thus, there is a problem on Friday, which makes this an incorrect answer.
Answer choices D and E are eliminated for the same reason. We are left with answer choices B and C.
(B) The setup the answer dictates is:
| |
Mon
|
Tue
|
Wed
|
Thu
|

According to the rules, Winona does not work on Mondays and Fridays. Thus, there is a problem on Friday, which makes this an incorrect answer.
We are left with answer choice C as the correct answer. Let's see why it is correct:

This setup does not violate any of the conditions, and is therefore a possible weekly work schedule.
