Uranium-236 undergoes nuclear fission to produce xenon-140, strontium-94 and two free neutrons.

Nuclide	Binding energy per nucleon / $MeV\text{MeV}$
$092236U^{236}_{\phantom{0}92}\text{U}$	7.6
$054140Xe^{140}_{\phantom{0}54}\text{Xe}$	8.3
$038094Sr^{\phantom{0}94}_{\phantom{0}38}\text{Sr}$	8.6

What is the energy released in this process?

$MeV177\text{ MeV}$

$MeV194\text{ MeV}$

$MeV1970\text{ MeV}$

$MeV3764\text{ MeV}$
