Which term means 'left'?

Explanation:
Understanding how side terms are formed in anatomy helps you map meanings to prefixes. Sinistr(o)- is the prefix that signals the left side, coming from Latin sinistra. It shows up in words like sinistral, meaning left-sided. The other options point to different things: spleno- relates to the spleen; stetho- to the chest; sten(o) means narrowing. So sinistr(o) is the correct way to express left.
