Is C the answer? I beg to differ. Let us analyze.
A) a lowering of employment rates triggered by a drop in investment, which causes people to cut consumer spending and start a cycle of layoffs leading back to even lower employment rates. ------
- ‘which causes’ refers to investment and hence flouts the relative pronoun touch rule.------- gone
B) a lowering of employment rates triggered by dropping investment, which causes people to cut consumer spending and starts a cycle of layoffs leading back to even lower employment rates. ---
same as A ---- ‘which causes’ refers to investment and hence flouts the relative pronoun touch rule .------ gone
C) falling employment rates triggered by a drop in investment, which cause cutbacks in consumer spending, starting a cycle of layoffs that lead to even lower employment rates. ---
same as A and BD) falling employment rates that are triggered by a drop in investment, causing people to cut consumer spending and starting a cycle of layoffs that lead back to even lower employment rates. ----
Avoids the touch rule pitfall by using the adverbial modifier that can modify a suitable theme in the preceding part – here, a cumulative effect of a resultant recession arising from drop in investment and drop in employment rates. However, unfortunately in the phrase - lead back – the back is redundant – goneE) falling employment rates that are triggered by a drop in investment, causing cutbacks in consumer spending and starting a cycle of layoffs leading to even lower employment rates.
Avoids the A, B, and C touch-rule trap and also omits the redundant 'back' E is my choice
