See explanation.

Quark properties are given in Table 44.5. An antiquark has charge and quantum numbers of opposite sign from the quark that it corresponds to. Simply add up the numbers for each of the quarks or antiquarks in the combination. a. charge = +0. Baryon number B = 1. Strangeness S = -1. Charm C = 0. b. charge = 0. Baryon number B = 0. Strangeness S = 0. Charm C = 1. c. charge = -1e. Baryon number B = 1. Strangeness S = 0. Charm C = 0. d. charge = -1e. Baryon number B = 0. Strangeness S = 0. Charm C = -1.
