STP-A is distinguished by having how many separate foil-shielded twisted pairs?

Explanation:
Shielding helps keep signals clean by blocking interference and reducing crosstalk between pairs. STP-A uses two twisted pairs that are each wrapped in their own foil shield, providing dedicated protection for those two paths. The other pairs aren’t individually foil-shielded, which keeps the design efficient while still delivering targeted EMI protection where it’s most needed. That’s why two shielded pairs is the correct description.
