大全 118

虚无飘渺

118 Art museums do not usually think of their collections as capital or consider the interest income that would be generated if a portion of the capital would have been invested in another form.

(C) be generated if a portion of the capital were

(D) be generated if a portion of the capital was（C）

why here should use "were" instead of "was"?

thanks.
