Option C — Only I, III and IV are correct.
Reducing trade barriers, reducing import/export taxes, and removing restrictions on foreign investment all stimulate globalisation. Statement II is incorrect as globalisation increases competition among producers, not reduces it.
Statement II is the key trick here — globalisation increases competition (as seen in the chapter's discussion of greater competition among local and foreign producers). Examiners test whether students can distinguish between measures that facilitate globalisation (liberalisation, removing barriers) and its effects (more competition, not less). Eliminating Statement II straightaway points to option C.
