Answer : 4. "Indeterminate"
Explanation :

Answer: D) Indeterminate Explanation: Indeterminate are those,which mathematics can’t determine. Because we don’t actually know which one is the exact answer for this due to having lots of results for this. Explanation:: Let us think by this analogy that, 0 / 1 = 0 0 / 2 = 0 ………… ……….. we can say 0 / n = 0 from this we can write, 0/0 = 0 Again, another analogy,(from limiting concept of 1/0 = infinity) 1 / 0 = +∞ or -∞ 2 /0 = +∞ or -∞ ……… .……. we can say 0 / 0 = ∞ Again, another analogy, 1 / 1 = 1 2/2 = 1 .…….. ……….. we can say, 0/0 = 1 Now, you see it’s confusing. Every analog is mathematically correct then which one is the right answer for 0/0.  Therefore Mathematics can’t determine this fact. So, 0/0 is indeterminate.
