According to the statement, if the OCPD rating is greater than 100 amperes, conductors can be selected either from the 75 degrees Celsius or degrees Celsius column of NEC Table 310.15(B)(16). The options given in the question are all lower than 100, so this condition doesn't apply. Therefore, the correct choice is simply the highest option, which is 90.
