Official Correct Choice:
Option D: \( 3.6 \times 10^3 \text{ C} \)
Concept:

Electric current is the rate of charge flow.

Formula:

$$ Q = I \times t $$

Solution:

  • Current \( I = 60 \text{ A} \).


  • Time \( t = 60 \text{ s} \).


  • Charge \( Q = 60 \times 60 = 3600 \text{ Coulombs} \).


  • Converting to scientific notation yields \( 3.6 \times 10^3 \text{ C} \).


Why other options are incorrect:

  • Opt B: Features a negative exponent, which implies micro-scale charge, not a massive 3600 Coulombs.


  • Opt A & C: Incorrect mathematical multiplication.
