Which nuclear equation represents a fusion reaction? A (}_{92)^238U+_(0)^1narrow _(93)^239Np+_(-1)^0e B (}_{92)^235U+_(0)^1narrow _(36)^92Kr+_(56)^141Ba+3_(0)^1n C. (}_{6)^14Carrow _(7)^14N+_(-1)^0e D (}_{1)^1H+_(1)^2Harrow _(2)^3He A B C D

The correct answer is D.<br /><br />A fusion reaction involves the combination of two or more smaller atomic nuclei to form a larger nucleus. In option D, the reaction ${}_{1}^{1}H+_{1}^{2}H\rightarrow _{2}^{3}He$ represents a fusion reaction where two hydrogen isotopes (deuterium and tritium) combine to form helium-3.
