Why is option B not the correct answer? (I understand why D is correct)

how come the potential difference became negative achanak se it'll decay as it is na?

When VA-Vb = 6V, Vq = 2v by solving equation of RC Circuit...so when Va-Vb is 0, Vp is 0...but Vq = 2V still remains so Vp-Vq is -2V well thats my logic

eh but thinking theoritically that graph should not be correct

hmmm maybe but the correct answer is that the negative part of the graph should start from -4V instead of -2V..do u have any idea why?

D is simple na When circuit is charging the heat lost from resistor is half the total energy given and when the circuit is discharging all the energy stored will be lost through the resistor because instantly Potential difference accross capacitor change nahi hona chahiye the magnitude Like before it was 4v and after it should also be 4v only ig the magnitude
