Identify the sequence that satisfies both conditions.

Let's evaluate the options containing three distinct elements (\, \%, \&$):\ast OptionB($ \% \, \$\&$): Fails Condition I because $\%$ is first.
* Option C (\ \, \& \, \%$):FailsConditionIIbecause$ \&$comesimmediatelyafter$ \
. * Option D ($\$ \, \% \, \&$): $\%$ is not first (satisfies Condition I). $\&$ does not come immediately after $\
; it comes after $\%$ (satisfies Condition II).
Therefore, Option D is the valid unique sequence.
