20. A nucleus of uranium undergoes fission.

${}_0^1n + {}_{92}^{235}U \rightarrow {}_{56}^{141}Ba + {}_{36}^{x}Kr + 3\,{}_0^1n$

What is correct about the number of nucleons x in the Kr nucleus and the ratio (binding energy per nucleon of Kr) / (binding energy per nucleon of Ba)?

	Number of nucleons x in Kr nucleus	Ratio
A.	92	Greater than 1
B.	92	Less than 1
C.	94	Greater than 1
D.	94	Less than 1
