Option (1) is a geometrical isomer and is not chiral.
Option 2) is a chiral compound and the chiral center is with S-configuration as follows:
Option 3) is a chiral compound and the chiral center is with R-configuration as follows:
Option 4) is not chiral since there is no asymmetric carbon atom.
Hence, option 3) is the correct answer.
