, is written as:

A) $I _ { t } = \bar { s } / \left[ F \left( K _ { t } , \bar { L } \right) \right]$
B) $l _ { t } = \bar { s } F \left( K _ { t } , \bar { L } \right)$
C) $I _ { t } = ( 1 - \bar { s } ) [ F ( K , \bar { L } ) ]$
D) $I _ { t } = \bar { s } - F \left( K _ { t } , \bar { L } \right)$
E) $I _ { t } = \bar { s } + F \left( K _ { t } , \bar { L } \right)$
