Visible and unobtrusive are not parallel adjectives.Hence the possibility of A,B,C is eliminated.

The noun equipment needs a appropriate singular verb and hence placing visible before equipment eliminates subject verb problem and solved the parallelism problem too.

In E it when used by is not parallel to the amount used by.


Answer is D
Resilience is a trait that manifests in an individual when he/she faces consistent failures motivating them to succeed in the end.
