Meaning around is shown by prefixes that indicate surrounding or encircling. Peri- signals around a boundary or near something, as in perimeter (the distance around) or pericardial (around the heart). Circum- means around as well, used in words like circumference (the distance around a circle) or circumscribe (to draw around). The other options pair prefixes that mean beneath or on/up, such as infra- (below), sub- (under), and epi- (upon). So the prefixes that convey around are peri- and circum-.
