Answer:
A. The plants are very expensive to build
Step-by-step explanation:
The nuclear energy has lot of benefits. The energy that the nuclear plants produce is in very high quantity, the energy is much more ecological, the fuel for it is relatively cheap, and they can produce energy for a very long period. One thing that can not be seen as a positive is that a nuclear energy plant is an enormous investment as it costs a lot. While this can be a stumbling block initially, on the long run it is nullified as the benefits surpass the initial costs.
