**Concept: The question tests on the basics of absolute value and equations in the format of a DS question**

**Solution:**

St (1)

Given

Distance (t, q) = distance (t, s) + distance (sq.)

t-q shall be positive, as it's the sum of two absolute values. So, t > q.

t > q and s is at the centre, thus q < s < t. **Sufficient.**

St (2)

It gives no information of s. s>q or s<q. Thus **Insufficient.**

**Option (A)**
