Given that A coin is tossed 14 times. Heads occurs 8 times and tails 6 times. The second and thirteenth tosses are heads.

Quantity A: Maximum number of heads that can occur in a row

We know that \(2^{nd}\) and \(13^{th}\) toss are heads and we have only 8 heads.
SO, 7 of them can occur together, which can include either the \(2^{nd}\) or the \(13^{th}\) toss.

Clearly, Quantity B(8) > Quantity A(7)

So, Answer will be B
Hope it helps!
