When a uranium-235 nucleus absorbs a neutron, it becomes unstable and undergoes fission. One possible fission process produces a xenon (Xe) nucleus, a strontium (Sr) nucleus, and 2 neutrons.

The fission process is represented by the nuclear equation below:

^{1}_{0}\text{n} + ^{235}_{92}\text{U} \rightarrow ^{140}_{54}\text{Xe} + {}^{A}_{Z}\text{Sr} + 2\,^{1}_{0}\text{n}

Which symbol represents the resulting strontium nucleus?

$3694Sr^{94}_{36}\text{Sr}$

$3894Sr^{94}_{38}\text{Sr}$

$3896Sr^{96}_{38}\text{Sr}$

$3892Sr^{92}_{38}\text{Sr}$
