(E) have chosen to use child care programs rather than quit
Ok, let's delve.
A decade is a period of ten years. The important point in the context is that the period of ten years is ended and is a thing of past. The chosen programs were a specific phenomenon that featured in the cited decade. Therefore, there is no need for a present perfect tense as if the event is continuing even today or the impact of that practice is spilling over in the present.
Therefore it is difficult to accept the present perfect "have chosen". Choices C and E flout verb tense format.
Not that the past perfect 'had chosen' is correct either. When one uses a past perfect, it is done to mainly indicate that it is earlier action than an another past action. The all important past tense required to legalize a past perfect is fatally missing in all the other choices A, B, and D. Parallelism issue is irrelevant without resolving the verb tense malady.
No choice seems to licit enough. Any choice with a simple past namely 'chose' would have been better.
