She starts on the 3rd rung and climbs 6 more &rarr;
She reaches the 3 + 6 = 9th rung
Since this is the middle rung, total number of rungs = 2&times;9&minus;1=172 &times; 9 &minus; 1 = 172&times;9&minus;1=17
So:
Statement I: Middle rung is 8th from top &rarr; Incorrect (It will be 9th from top or bottom)
Statement II: Total rungs = 17 &rarr; Correct
Hence option b is correct.
