Answer:

D.
(79)/(6)

Explanation:

$\bigg( (7)/(2) - (1)/(3) \bigg).( - 2)^(2) + (1)/(2) \\ \\ = \bigg( (7 * 3 - 1 * 2)/(2 * 3) \bigg).4 + (1)/(2) \\ \\ = \bigg( (21 - 2)/(6) \bigg).4 + (1)/(2) \\ \\ = (19)/(6) * 4 + (1)/(2) \\ \\ = (19)/(3) * 2 + (1)/(2) \\ \\ = (38)/(3) + (1)/(2) \\ \\ = (38 * 2 + 1 * 3)/(3 * 2) \\ \\ = (76 + 3)/(6) \\ \\ = (79)/(6)$
