Correct option is D
The shirts manufactured by the companies C1 = 190 + 225 + 240 + 215 + 205 = 1075
The shirts manufactured by the companies C2 = 226 + 244 + 175 + 235 + 210 =1090
The shirts manufactured by the companies C3 = 184 + 214+ 235 + 260 + 265 = 1158
The shirts manufactured by the companies C4 = 202 + 202 + 275 + 200 + 245 =1124
