In a square of opposition, match List I (Proposition given as false) with List II (Resultant) and choose the correct answer from the options given below.

List I

i.'A' being given false

ii.'E' being given false

iii.'I' being given false

iv.'O' being given false

List II

a.'E' is false

b.'E' is true

c.'I' is undetermined

d.'I' is true

Ai-a, ii-d, iii-b, iv-c

Bi-b, ii-c, iii-a, iv-d

Ci-c, ii-d, iii-b, iv-a ✓ Correct

Di-d, ii-b, iii-c, iv-a

Correct answer: (C) i-c, ii-d, iii-b, iv-a

Explanation

A given false leaves its subaltern I undetermined, so i pairs with c.

E given false makes its contradictory I true, so ii pairs with d.

I given false makes its contradictory E true, so iii pairs with b.

O given false makes A true and its contrary E false, so iv pairs with a.

The matching is i-c, ii-d, iii-b, iv-a.
