The charge on capacitor at any time t is q=qmax​(1−e−t/CR)
As the qmax​ of both curves is the same so both capacitors will be charged to the same charge.
As (2) curves take more time for maximum charging so the time constant of curve (2) is greater than (1). i.e, τ2​>τ1​⇒C2​R2​>C1​R1​
As qmax​ is same for both curve so C1​E1​=C2​E2​
Since C1​ and C2​ are different so emf of both cells may be different.
now E1​=(C2​/C1​)E2​>(R1​/R2​)E2​
If R1​>R2​ , then E1​>E2​.

Point A is evident from the graph itself.
For point C, E=IR. I is different because time for charging is different for both of them.

Read the following text and answer the following questions on the basis of the same: Supercapacitor: Super capacitor is a high capacity capacitor with a capacitance value much higher than normal capacitors but with lower voltage limits. Such capacitors bridges the gap between electrolytic capacitors and rechargeable batteries. In automobile, bus, train, crane, elevator such capacitors are used for regenerative braking, short term energy storage or burst-mode power delivery. Super capacitors have many advantages over batteries: they are very low weight and generally don't contain harmful chemicals or toxic metal. They can be charged and discharged innumerable number of times without ever wearing out. The disadvantage is that super capacitors aren’t well-suited for long-term energy storage. The discharge rate of super capacitors is significantly higher than lithium-ion batteries; they can lose as much as 10-20% of their charge per day due to self discharge.Self-discharge rate of Supercapacitors
