As far as I understund the FOR loop will never executed, because of array lenght 0.
This means Numeric value out is never assigned any value.
But how do you know numeric out is 0? It can be anything by chance in the range of an integer?
Is there a LabVIEW rule for outputs for LOOPS with zero iterations?
Or is there a default for never assigned output values?
(Sorry for my limited English Grammar 😉

I think it is A. The for loop will never execute due to the empty string array

@Andreas23, since no value is assigned to the tunnel, Numeric Value Out gets the default numeric value, which happens to be 0.

Answer: A.  Nice one DavidCorney, ashwinilele, kirthika101, J_M_M, Juvin, dfjuggler, LordNobady, crossrulz, MrStevenUND, nik35324, gnshmrthy & rgbernatchez.

Remembering that FOR loops are lasy (they will always go for the least number of iterations) and that if they iterate 0 times that default values are passed to any output tunnels.

A nice link dfjuggler thanks.
