Step 1: A pregnancy luteoma is a hormone-driven, benign ovarian overgrowth seen in gestation, fueled by the high hCG of pregnancy rather than being a true cancer.
Step 2: On examination or imaging it commonly shows up in both ovaries as solid, multinodular swellings, confirming the bilateral nature.
Step 3: Under the microscope the ovarian stroma is taken over by sheets of luteinized cells, which matches the cellular description in the options.
Step 4: Because it shrinks on its own once the baby is delivered and requires no surgery, it is benign and self limiting. With every individual statement valid, the combined choice is right.
