A content label sometimes depends on information only available at runtime, or the meaning of a View might change over time. For example, a Play button might change to a Pause button during music playback. In these cases, to update the content label at the appropriate time, we can use:
A) View#setContentDescription(int contentDescriptionResId)
B) View#setContentLabel(int contentDescriptionResId)
C) View#setContentDescription(CharSequence contentDescription)
D) View#setContentLabel(CharSequence contentDescription)
