a) In order to light up the LED, what should Pin 1 and Point B be connected to?

Ans: Pin 1 connected to (5V / GND), Point B connected to (5V / GND)

b)What is the currency shown on the multimeter? Is the current flowing out from Pin 2 or flowing into Pin 2?

c) Replace the led and resistor with a multi-meter and measure the current again. Is

the current flowing out from Pin 2 or flowing into Pin 2.

The above method will allow you to know the maximum current sink by the IC.
