Question

what is one primary factor that deters many individuals from pursuing a ph.d.?
not having family support
substantial financial commitment
limited availability of doctoral programs

Explanation:

Pursuing a Ph.D. often requires a long - term financial commitment. This includes tuition fees (even with some funding, there may be additional costs like research materials, conference fees), and the opportunity cost of not being in full - time employment for several years. Family support, while important, is not as universally a primary deterrent as financial aspects. Doctoral programs are available in many fields and institutions, so limited availability is not a major factor for most.

Answer:

substantial financial commitment
