The answer is choice (1).
In case you're interested in the solution for future reference:
-- Density = (mass) / (volume)
-- The scale shows that the mass of the sample is 60 grams.
-- The graduated cylinder has 24 mL in it without the sample.
The graduated cylinder has 34 mL in it with the sample.
The volume of the sample is (34mL - 24mL) = 10 mL .
-- Density = mass/volume = 60g / 10mL = 6 g/mL
