I would say that answer is A

statement 1 states that q=-s thus q <0>0. it means that 0 is included into the (q;s) distance and is located strictly in the middle.
r being also inside (q;s), r is closest to 0 because distance (r;0) or (0;r) is smaller than (-s;0) or (0;s).

statement 2 does not provide enough info. Zero could be anywhere inside (q;t) or even before q (i.e. q, r, s, t are all positive numbers).
