Pick the correctbest statement related to the basic 555 asta
     Pick the correct/best statement related to the basic 555 astable.  a) C charges through the parallel combination of (R_A + R_B) and R1.  b) C charges through R_A and R_B, and discharges through R_B, which is why the duty cycle can never be 50%  c) Many different combinations of values for R_A, R_B, and C, can produce any desired frequency and duty cycle.  d) For a desired frequency and duty cycle, there is only one combination of R_A, R_B, and C that will work.   
  
  Solution
Option- b
