Gravitational lensing of distant objects by closer galaxies indicates that

(a)   the amount of visible matter in the galaxies accounts for only 10% of the total mass producing the lensing.
(b)   the amount of visible matter in the galaxies is sufficient to account for the gravitational lensing.
(c)   the amount of visible matter in the galaxy is about 10 times too much to account for the observed lensing, leading to the idea of negative gravitation within such large-scale structures.
