, and 118.7 g mol

^{-1}

, respectively. The possible identities are Al, Zn, and Sn. Which assignment of elements to lines is most consistent with the data? (a)

A = \text{Al},\; B = \text{Sn},\; C = \text{Zn}

(b)

A = \text{Al},\; B = \text{Zn},\; C = \text{Sn}

(c)

A = \text{Sn},\; B = \text{Zn},\; C = \text{Al}

(d)

A = \text{Zn},\; B = \text{Al},\; C = \text{Sn}
