on water resources has resulted both from expanding
development, changes in climate, and from pollution,
so that the future supply in some of the more arid
areas is a concern going forward.
(A) both from expanding development, changes in
climate, and from pollution , so that the future
supply in some of the more arid areas is a
concern going forward
(8) both from expanding development or changes in
climate, and pollution, so that future supplies in
some of the more arid areas are a concern
(C) from expanding development, changes in
climate, and also from pollution, so that the
future supply in some of the more arid areas is a
matter of concern going forward
(D) from expanding development, changes in
climate, and pollution, so that future supplies in
some of the more arid areas are a concern
(E} from expansion of development, changes in
climate, and from pollution, so that supplies

正确答案是D,我排D的原因在于：future supplies(复数）.....are a concern（单数），难道复数主语后面可以跟单数的表语么？求大神解答语法点，谢谢！
