P: But there is a common thread in their work.
Q: In economic jargon it's termed as externality.
R: Productive activity often has spillovers, meaning that it can impact an unrelated party.

Explanation
P notes the common thread between Romer's and Nordhaus's work (linking to S1's "two separate areas"); R defines that thread (spillovers); Q names it ("externality"); S states that both studied externalities — setting up S6 on the topical issue for India. The chain is P-R-Q-S. Hence (B).
