By showing that South Africa does not have a free market and is in fact a kind of collectivist welfare state for Whites only, Sowell argues that American conservatives have no valid ideological grounds to be in sympathy with the Pretoria regime.
(A) to be in sympathy with
(B) to sympathize with

(D) that they should sympathize with

[spoiler]I actually chose B as well, but in retrospect, I think C would be the better choice because of parallelism... "showing" and "sympathizing" need to be parallel here.[/spoiler]

IMO C

[cramya]

grounds for something(in this sentence the something is symphathizing) is idiomatic usage meaning the basis or cause for something/some action

Also parallelism like one of the users pointed out

Hope this helps! Hence C

"To sympathize" suggests that the sympathy may not be occuring, may just be a potential. Sowell is commenting on a sympathy that is indeed ongoing or active. Only " For sympathazing" conveys this "ongoingness".
