Both options A and C are incorrect. The possessive in A showing ownership is in singular form. Therefore combining it with plural noun " testimonies' is incorrect.
Furthermore, the placement of possessive marker in C is incorrect too because the possessor is in singular form.
<em>A. the </em><u><em>witness's</em></u><em> </em><em>testimonies</em>
The underlined is a singular form of a possessive common noun. It should be in a plural form, considering the <em>bolded </em>text above( testimonies).
<em>B. the </em><u><em>witnesses'</em></u><em> </em><em>testimonies</em>
This is the correct option. The undelined is properly personalized and it is also pluralized to match the bolded text above.
