Share support between two liquids

A uniform object of density 1100 kg/m³ floats fully immersed across an interface between deep immiscible liquids: 900 kg/m³ above and 1400 kg/m³ below. The available depths accommodate both portions, orientation is stable, and there is no tether or contact.

What fraction of its volume lies in the lower liquid?

Organize the givens & assumptions

ρbody = 1100 kg/m³
ρupper = 900 kg/m³
ρlower = 1400 kg/m³
Fully immersed

Settled hydrostatic equilibrium in uniform gravity; stable stated orientation, no contact forces unless stated, negligible air buoyancy and surface tension, no absorption, trapped gas or spilling.

A $11/14$
B $0.50$
C $0.40$
D $0.60$
