A truth conditional is only concerned in the truth of a statement, not so much in whether or not that statement makes sense realistically. A hypothesis is a theorical supposition or explanation that is tentatively accepted in order to understand certain events or phenomena, and to offer direction for further investigation. The conclusion is what we get in the end.
Whit this explained, we can see how the last option is the correct one
Yesterday was Tuesday if tomorrow is Thursday.
Hypothesis: Tomorrow is Thursday.
Conclusion: Yesterday was Tuesday.
