Nevertheless, Naomi's reply amounts to the definition of discrimination under Section 39 (1)(c) and (3)(c) of the Equality Act 2010 (see also section (4)), since it explicitly sets unequal standards for men and women applying to the same job -- namely, that a woman must be the absolute best applicant in order to qualify for a job, whereas a man must merely match the best woman. Such an equal playing field is discriminatory and would be grounds for criminal action.
So, in that sense, the logic that "one attempts to opt for choices that are likely to create the least problems" should certainly not lead to always picking the man out of equal men and women, since such a business would be liable at the very least for hefty fines -- which, I suggest, might be a greater problem than employing a woman who may, possibly, end up pregnant at some point.
