I think the answer is Option (C) all rite...

L & C are always 180 degrees out of phase
The catch is there isn't any practical circuit in the world which doesn't have any resistance...

So option 'a' ( C only) & 'd' (L only) is practically not possible... (Theoretically yes... In that case its 90 degress out of phase...)

R & C also has very little probability (But some alrite... Although I can't think of a situation ) to go 90 degrees out of phase...

Anyway L&C is the safest answer as they will never have 90 degrees phase diff...

For Solution, wrong answere

Here are some more cool PI facts:-

1. In the Greek alphabet, p is the 16th letter (and 16 is the square of 4). In the English alphabet, p is also the 16th letter, and I is the 9th letter (the square of 3). Add them up (16 +9), and you get 25 (the square of 5). Multiply them (16 x 9), and you get 144 (the square of 12), divide 9/16, and you get .5625 (the square of .75). It’s no wonder that they say, “ Pi are squared.

2. If you take 10 million random digits, statistically on average you would expect 200 cases where you get 5 digits in a row the same. If you take 10 million digits of Pi, you get exactly 200

3. There is no zero in the first 31 digits of Pi.

4. Write the letters of the English alphabet, in capitals, clockwise around a circle, and cross out the letters that have right-left symmetry, A, H, I, M, etc. The letters that remain group themselves in sets of 3, 1, 4, 1, 6
