Which example illustrates the passive voice in the simple present tense?

The selected example illustrates the passive voice in the simple present tense effectively. In passive voice constructions, the focus shifts from the subject performing the action to the subject receiving the action. The simplicity of this structure in the present tense is characterized by the verb "to be" in the present tense (is) combined with the past participle of the main verb (taken).

In this case, "She is taken" indicates that "she" is the recipient of whatever action is implied by "to take." The action is not being performed by "she," but rather, she is experiencing or being subjected to the action. This structure emphasizes the subject's state or condition instead of the action itself.

Other options do not meet the criteria for passive voice in the simple present tense. For instance, "He takes" and "She is taking" are both active voice constructions, where the subjects are performing actions rather than receiving them. Meanwhile, "He wrote" is in the past tense and also represents an active voice form. Hence, the focus of the question on identifying the passive voice in the simple present tense is aptly fulfilled by the choice of "She is taken."
