Let us find out the number of ways in which an outfit can be selected. An outfit is defined as a pair of shoes, an upper wear, and a lower wear. A pair of shoes can be selected in 3 ways. There are 4 pants and 3 half-pants. A pant or a half-pant can be selected in 7 ways. A shirt can be selected in 6 ways. A sweater can be selected in 3 ways. A shirt and a sweater can be selected in 18 ways. Therefore, an upper wear can be selected in 6+3+18 = 27 ways. A jacket can be worn in 1(no jacket is selected) + 2 (one of the 2 jackets is selected) = 3 ways. Therefore, the total number of ways in which an outfit can be worn = 3*7*27*3 = 1701. As the answer is not among the given choices, option D is the right answer.
